fix: i2c: a385-amc: disable external I2C: prevent bus contention
A385-AMC has external I2C access via AMC connector, which is needed to:
- detect remote MSYS PCIe Gen settings (via MSYS i2c EEPROM)
- configure MSYS Sample at reset values via remote i2c devices
When A385 is mastering the I2C bus in parallel with MSYS platform,
I2C bus contention sometimes occur, which leads to invalid board
configuration for A385 (invalid Board ID from EEPROM, etc..)
To avoid this issue, this patch currently disable external I2C
access on A385-AMC side (via GPIO)
