Active state requests are sent immediately to the mailbox controller,
Drive by note, mailbox went away from this code so grep 'mailbox' or
'mbox' on these patches should come up with zero hits.
while sleep and wake state requests are cached in this driver to avoid
taxing the mailbox controller repeatedly. The cached values will be sent
to the controller when the rpmh_flush() is called.
