soc/intel/common: Fix bugs for GPIO_LOCK_UNLOCK

Per the Intel External Design Specification (doc #618876), the opcode
for GPIO_LOCK_UNLOCK is 0x13.  This commit fixes a bug where the opcode
was defined as 13 decimal instead of hexadecimal.  Additionally, it
fixes another issue where the `pcr_execute_sideband_msg()` function
doesn't actually write the data when this opcode is selected.

BUG=b:191189275
BRANCH=None
TEST=With additional code that uses this opcode, verify that the lock
functionality works by locking a pad in firmware and attempting to
modify the configuration of the pad from the OS.
