soc/amd/common/block/i2c: Move SoC agnostic parts into common
The logic behind I2C bus initialization, I2C MMIO base address getter
and setter, I2C bus ACPI name resolution are identical for all the AMD
SoCs. Hence moving all the SoC agnotic parts of the driver into the
common driver and just configure the SoC specific parts into individual
I2C drivers.
BUG=None
TEST=Build Dalboz and Grunt. Boot to OS in Dalboz. Ensure that the I2C
peripherals are detected as earlier in Dalboz. Verify some I2C
peripheral functionality like trackpad and touchscreen.
