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.
