soc/intel/jasperlake: Add offsets for pad locking
This commit simply adds the offset for the PADCFGLOCK register for the
Intel Jasper Lake platform. This enables pads to be locked.
BUG=b:191189275
BRANCH=None
TEST=Enable pad locking on lalala by calling `gpio_lock_pad` and verify
that the pad configuration is locked and cannot be manipulated from the
OS.
