Fix an error in commit afd4a6522 which meant that writing a zero
to the RW bits in the PMCR wouldn't actually clear them. (Error
spotted by Andrzej Zaborowski.)

This fixes the bug Andrzej pointed out in comments on the earlier
patch; sorry about this error. I opted to use a separate & rather
than merging the bit-clearing in with the W1C handling for clarity.
