sm8250-common: Reapply "Set ro.boot.hardware.revision based on RF version"

ro.boot.hardware.revision is used in fastbootd UI, getvar hw-revision
output and Settings app.

Set based on the RF version so external tools can use it to flash
the correct firmware variant and show the HW variant in Settings.
