i2c: davinci: Split functions into two parts for future DM support
The i2c driver will be converted to support device model. In preparation
for that change split the various functions into two parts. This will
allow device model specific driver to reuse the majority of the code from
the non device model implementation.
Also rename the probe function to probe_chip to better reflect its
purpose.

Add ARM errata workaround 852421 and 852423 for Cortex-A17
ARM errata 852421 and 852423 applies to r1p0, r1p1 and r1p2
revisions of Cortex-A17 processors. These workarounds
exist in Linux kernel and I thought it would be better
to add them in to U-Boot.
Add support for clocks needed by MACs to ast2500 clock driver.
The clocks are D2-PLL, which is used by both MACs and PCLK_MAC1 and
PCLK_MAC2 for MAC1 and MAC2 respectively.
The rate of D2-PLL is hardcoded to 250MHz -- the value used in Aspeed
SDK. It is not entirely clear from the datasheet how this clock is used
by MACs, so not clear if the rate would ever need to be different. So,
for now, hardcoding it is probably safer.
The rate of PCLK_MAC{1,2} is chosen based on MAC speed selected through
hardware strapping.
So, the network driver would only need to enable these clocks, no need
to configure the rate.

Add Device Model based I2C driver for ast2500/ast2400 SoCs.
The driver is very limited, it only supports master mode and
synchronous byte-by-byte reads/writes, no DMA or Pool Buffers.
This driver uses Generic Pinctrl framework and is compatible with
the Linux driver for ast2500: it uses the same device tree
configuration.
Not all pins are supported by the driver at the moment, so it actually
compatible with ast2400. In general, however, there are differences that
in the future would be easier to maintain separately.
