p54: re-enable power save feature
This patch re-enables p54's power save features and adds a workaround
which temporarily alters the device's power state in order to allow
ps-polls to be sent and buffered data to be retrieved during psm.
(Incorporates patch originally posted as "p54: fix beacon template dtim
IE corruption". -- JWL)
