soc/amd/genoa: add I2C support
The Genoa SoC has 6 I2C controllers. In order to support those, select
SOC_AMD_COMMON_BLOCK_I2C and implement the SoC-specific functions and
data structures needed by the common AMD I2C code. Since the common AMD
I2C code also reports if the controller is enabled or not in the SSDT,
change the corresponding DSDT code to use this information. In this
patch the I2C pad control registers don't get configured by coreboot yet
and we rely on ABL already having those set up correctly which seems to
be an assumption that the reference firmware is making too. PPR #55901
Rev 0.26 was used as a reference for the I2C controllers and the GPIO
pins being used.
