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.
