rockchip: mkimage: rewrite padding calculation for SD/MMC and SPI images
In (first) breaking and (then) fixing the rkspi tool, I realised that
the calculation of the required padding (for the header-size and the
2K-in-every-4K SPI layout) was not as self-explainatory as it could
have been. This change rewrites the code (using new, common functions
in rkcommon.c) and adds verbose in-line comments to ensure that we
won't fall into the same pit in the future...
Tested on the RK3399 (with has a boot0-style payload) with SD/MMC and SPI.

rockchip: spi: rewrite rkspi_set_clk for a more conservative baudrate setting
The baudrate in rkspi was calculated by using an integer division
(which implicitly discarded any fractional result), then rounding to
an even number and finally clamping to 0xfffe using a bitwise AND
operator. This introduced two issues:
1) for very small baudrates (overflowing the 0xfffe range), the
bitwise-AND generates rather random-looking (wildly varying)
actual output bitrates
2) for higher baudrates, the calculation tends to 'err towards a
higher baudrate' with the actual error increasing as the dividers
become very small. E.g., with a 99MHz input clock, a request
for a 20MBit baudrate (99/20 = 4.95), a 24.75 MBit would be use
(which amounts to a 23.75% error)... for a 34 MBit request this
would be an actual outbout of 49.5 Mbit (i.e. a 45% error).
This change rewrites the divider selection (i.e. baudrate calculation)
by making sure that
a) for the normal case: the largest representable baudrate below the
requested rate will be chosen;
b) for the denormal case (i.e. when the divider can no longer be
represented), the lowest representable baudrate is chosen.
Even though the denormal case (b) may be of little concern in real
world applications (even with a 198MHz input clock, this will only
happen at below approx. 3kHz/3kBit), our board-verification team kept
complaining.

rockchip: spi: rk_spi: dynamically select an module input rate
The original clock/bitrate selection code for the rk_spi driver was a
bit limited, as it always selected a 99MHz input clock rate (which
would allow for a maximum bitrate of 49.5MBit/s), but returned -EINVAL
if a bitrate higher than 48MHz was requested.
To give us better control over the bitrate (i.e. add more operating
points, especially at "higher" bitrate---such as above 9MBit/s), we
try to choose 4x the maximum frequency (clamped to 50MBit) from the
DTS instead of 99MHz... for most use-cases this will yield a frequency
of 198MHz, but is flexible to go beyond this in future configurations.
This also rewrites the check to allow frequencies of up to half the
SPI module rate as bitrates and then clamps to whatever the DTS allows
as a maximum (board-specific) frequency and does away with the -EINVAL
when trying to select a bitrate (for cases that exceeded the hard
limit) and instead consistently clamps to the lower of the hard limit,
the soft limit for the SPI bus (from the DTS) or the soft limit for
the SPI slave device.

rockchip: clk: rk3399: fix off-by one during rate calculation in i2c/spi_set_rate
For the RK3399, i2c_set_rate (and by extension: our spi_set_rate,
which had been mindlessly following the template of the i2c_set_rate
implementation) miscalculates the rate returned due to a off-by-one
error resulting from the following sequence of events:
1. calculates 'src_div := src_freq / target_freq'
2. stores 'src_div - 1' into the register (the actual divider applied
in hardware is biased by adding 1)
3. returns the result of the DIV_RATE(src_freq, src_div) macro, which
expects the (decremented) divider from the hardware-register and
implictly adds 1 (i.e. 'DIV_RATE(freq, div) := freq / (div + 1)')
This can be observed with the SPI driver, which sets a rate of 99MHz
based on the GPLL frequency of 594MHz: the hardware generates a clock
of 99MHz (src_div is 6, the bitfield in the register correctly reads 5),
but reports a frequency of 84MHz (594 / 7) on return.
To fix, we have two options:
* either we bias (i.e. "DIV_RATE(GPLL, src_div - 1)"), which doesn't
make for a particularily nice read
* we simply call the i2c/spi_get_rate function (introducing additional
overhead for the additional register-read), which reads the divider
from the register and then passes it through the DIV_RATE macro
Given that this code is not time-critical, the more readable solution
(i.e. calling the appropriate get_rate function) is implemented in this
change.

configs: sama5d3xek: add default config for CMP board
The sama5d36ek CMP board is the variant of sama5d3xek board.
It is equipped with the low-power DDR2 SDRAM, PMIC ACT8865, and
some power rails. The board is mainly used to measure the power
consumption. As all those changes are done in at91bootstrap,
in U-Boot, only use another device tree file, no code needed
to change.
As there is additional power consumption when enbling the USB
Host and USB device, for the power consumption measurement
intention, disable the USB host and device.

board: sama5d2_xplained: clean up macb init code
Because the MACB driver supports the driver model and device tree,
the pins configuration and clock enabling are handled by the
pinctrl driver and clock driver, remove this hardcoded init code.
The USB Ether init code is removed as well.
