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