commit 34a081761e4e3c35381cbfad609ebae2962fe2f8 upstream.
In some cases, the IPA hardware needs to request the always-on
subsystem (AOSS) to coordinate with the IPA microcontroller to
retain IPA register values at power collapse. This is done by
issuing a QMP request to the AOSS microcontroller. A similar
request ondoes that request.
We must get and hold the "QMP" handle early, because we might get
back EPROBE_DEFER for that. But the actual request should be sent
while we know the IPA clock is active, and when we know the
microcontroller is operational.

Finally, rename "ipa_clock.c" to be "ipa_power.c" and "ipa_clock.h"
to be "ipa_power.h".
