These options only apply when not using DM_I2C. When using device
trees, the dt will enable and control the speeds of the I2C
controller(s) and these configuration options have no effect.
So disable them in DM_I2C mode. Otherwise they show up as decoys, and
make it look like one is enabling I2C controllers and setting the speed
when really it's doing nothing.
However, a system using a SPL build will not use DM_I2C in the SPL, even
if DM_I2C is enabled for the main u-boot. And so the SPL might use the
kconfig based I2C speed controls while the main u-boot does not.

Add Xilinx AXI I2C controller driver based on the Linux i2c-xiic driver.
This driver is stripped of all the IRQ handling and uses pure polling,
yet tries to retain most of the structure of the Linux driver to make
backporting of fixes easy.
Note that the IP has a known limitation on 255 bytes read and write,
according to xilinx this is still being worked on [1].

These support the flat device tree. We want to use the dev_read_..()
prefix for functions that support both flat tree and live tree. So rename
the existing functions to avoid confusion.
In the end we will have:
1. dev_read_addr...() - works on devices, supports flat/live tree
2. devfdt_get_addr...() - current functions, flat tree only
3. of_get_address() etc. - new functions, live tree only
All drivers will be written to use 1. That function will in turn call
either 2 or 3 depending on whether the flat or live tree is in use.
Note this involves changing some dead code - the imx_lpi2c.c file.

This patch allows using i2c commands (e.g. "i2c probe", "i2c md", etc)
without the need to first select the bus number with e.g. "i2c dev 0".
This is the "i2c" command behavior similar to the one from pre DM, where
by default bus 0 was immediately accessible.
