I would like to remove the fixes tag as there is a TF_A bug. The TF_A uses i2c8 pins for
PMIC control and Kernel uses I2C2 for PMIC control.

TF-A not reconfiguring i2c8 pins during suspend state once the kernel overrides the i2c2 pin.

Also, I will send v2 update the commit message to use i2c8 bus for controlling PMIC across
bootloader and Kernel.

Cheers,
