Add support for Direct Access Controller mode of Cadence QSPI. This
allows MMIO access to SPI NOR flash providing better read performance.
Direct mode is only exercised if AHB window size is greater than 8MB.
Support for flash address remapping is also not supported at the moment
and can be added in future.
For better performance, driver uses DMA to copy data from flash in
direct mode using dma_memcpy().

Current Cadence QSPI driver has few limitations. It assumes all read
operations to be in Quad mode and thus does not support SFDP parsing.
Also, adding support for new mode such as Octal mode would not be
possible with current configuration. Therefore move the driver over to spi-mem
framework. This has added advantage that driver can be used to support
SPI NAND memories too.
Hence, move driver over to new spi-mem APIs.
Please note that this gets rid of mode bit setting done when
CONFIG_SPL_SPI_XIP is defined as there does not seem to be any user to
that config option.

spi: prevent overriding established bus settings
The SPI stack relies on a proper bus speed/mode configuration
by calling dm_spi_claim_bus(). However the hitherto code
allowed to accidentally override those settings in
the spi_get_bus_and_cs() routine.
The initially established speed could be discarded by using
the slave platdata, which turned out to be an issue on
the platforms whose slave maximum supported frequency
is not on par with the maximum frequency of the bus controller.
This patch fixes above issue by configuring the bus from
spi_get_bus_and_cs() only in case it was not done before.

spi: nxp_fspi: new driver for the FlexSPI controller
This is a port of the kernel's spi-nxp-fspi driver. It uses the new
spi-mem interface and does not expose the more generic spi-xfer
interface. The source was taken from the v5.3-rc3 tag.
The port was straightforward:
- remove the interrupt handling and the completion by busy polling the
controller
- remove locks
- move the setup of the memory windows into claim_bus()
- move the setup of the speed into set_speed()
- port the device tree bindings from the original fspi_probe() to
ofdata_to_platdata()
There were only some style change fixes, no change in any logic. For
example, there are busy loops where the return code is not handled
correctly, eg. only prints a warning with WARN_ON(). This port
intentionally left most functions unchanged to ease future bugfixes.
This was tested on a custom LS1028A board. Because the LS1028A doesn't
have proper clock framework support, changing the clock speed was not
tested. This also means that it is not possible to change the SPI
speed on LS1028A for now (neither is it possible in the linux driver).

we support having the SPL loaded from either the traditional 8KB SD
card/eMMC offset, or from the alternative location at 128KB. However the
sector to find the U-Boot image was still hard-coded at compile time,
and had to be adjusted for one of the two choices.
Since we can actually override the function to return the sector offset,
we can just check the boot source byte there to select the proper offset
based on from where the SPL was loaded.
This allows the very same binary image to be loaded from either 128KB or
8KB, with the U-Boot proper image always being located just behind the SPL.

NOR flash, and loads at most 32KB. This is a similar situation as on MMC,
so consequently we create our "joint" image (SPL + U-Boot proper) with
that 32KB offset during the build.
