soc/intel/baytrail: add _HRV to I2C ACPI devices
For some reason, the Windows i2c drivers won't attach without
_HRV (hardware version) defined for the i2c controllers.
Add it, using value taken from Intel baytrail/valleyview edk2
reference code.
TEST=boot Windows 10/11 on google/rambi, verify i2c drivers load
properly.
