Karthikeyan Ramasubramanian fec4db954e soc/amd/cezanne: Configure I2C Pad RX Select through devicetree
Some of the I2C buses are required to operate at different voltage level
compared to other I2C buses eg. I2C bus to Google Security Chip (GSC)
should be at 1.8V level. By default, all the I2C buses are initialized
to operate at 3.3 V. Add support to configure I2C pad RX select through
devicetree and update the concerned devicetree.

BUG=b:188538373
TEST=Build and boot to OS in Guybrush. Ensure that the communication
with GSC is fine. Build Majolica mainboard.
