PrmPkg: Remove PRM Module Update Lock
Per latest design direction, we've abandoned treating the PRM Module Update Lock as an exported object. There was concern sharing the PRM module address space (where the lock structure resided in a data section) with the OS kernel mode driver. The lock will now be entirely maintained in OS context with interaces to control the lock available to ASL (for _DSM invocation) and OS native code (for direct call).
