platform/x86/amd: pmc: Use release_mem_region() to undo request_mem_region_muxed()
Muxed (mem) regions will wait in request_mem_region_muxed() if the region
is busy (in use by another consumer) during the call.
In order to wake-up possibly waiting other consumers of the region,
it must be released by a release_mem_region() call, which will actually
wake up any waiters.
release_mem_region() also frees the resource created by
request_mem_region_muxed(), avoiding the need for the unmatched kfree().
