-Added default requirements field in PmRequirements structure
-Added notification of master when primary processor switches from
forced powerdown to active state. Master has to make sure that all
default requirements gets set before primary processor enters active
state.
-In PmMasterNotify, changed behavior when wake event is received:
if primary processor is in sleep state, everything works as before,
if primary processor is in forced powerdown, default requirements
are requested and configured
-In PmRequirementReleaseAll added a check is master using slave and
if yes, usage flag and requirements are cleared
-Added PmRequirementRequestDefault function called before primary
processor switches from forced powerdown to active. Function
automatically requests all default requirements which are later
configured by PmRequirementUpdateScheduled
-In PmRequirementUpdateScheduled when swapping requirements added
a check whether master has default requirements. If yes, default
reqs are saved as next reqs instead of current. Default requirements
have priority over current requirement. Example: RPU0 keeps boot code
in one TCM bank and when booted, during the runtime, it keeps that
bank in retention. For this bank RPU0 should have default requirements
= on state, and when it boots up it can request retention. If default
requirements wouldn't exist, it would have to request for boot bank to
switch from retention to on before calling self suspend, just to get
on state in scheduled reqs
