-GpuPP now has its own PmSlave derived structure and the FSM
(new structure is added because there is no peripheral with
exactly the same behavior - Usbs have also their own power island,
but compared to them GpuPPs do not have wake-up capabilities
through GIC Proxy, and GpuPPs depend on FPD while LPD is
considered always-on)

-Added PM_CAP_POWER as generic capability (defined in pm_defs).
-Slaves' FSMs should define PM_CAP_POWER capability in states which
require power parent to be ON before the state is entered. This
capability has no effect if slave node does not have power parent
-Powering up parent of a slave is done automatically by the
framework before the FSM of a slave is triggered to change the
state (slave's FSM should assume all prerequisites regarding power
are configured before FSM is triggered)
-Added PM_CAP_POWER capability in ON state of standard fsm (used for
SATA)

-There was a bug in pmu-fw/pm binding through IPIs, because of
which in case of multiple IPI interrupts generated simultaneously
only first interrupt was handled, other interrupts were lost
-The bug existed because PM handles one request in each
XPfw_PmIpiHandler invocation, and pmu-fw clears all bitfields
in ISR register after PM handles request. Therefore, if multiple
bits were set in ISR register (simultaneous IPI interrupts), only
first one was handled and other bits were just cleared
-XPfw_PmIpiHandler now returns status and through an argument
pointer an IPI mask of master whose request has been handled
-In xpfw_user_startup.c/PmIpiHandler, return of XPfw_PmIpiHandler
is checked. If PM successfully handled IPI, only the bitfield of
master whose request is handled is set (only that IPI interrupt
is cleared). If something went wrong in PmIpiHandler/IPI0 case,
we clear all bits set in ISR register, to avoid system hanging on
this interrupt handler
-In pm_master, a check whether the master owns given mask was
performed by using '==' instead '&'. Therefore, when 2 masters
generated interrupt at the same time, PM function that checks
whether the IPI is PM related returned that the ISR value does
not match any master. This bug is fixed

-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

Before, there was a check at the very beginning to see if current state
is having exact required capabilities. However, state should be checked
for having all required capabilities and not for having exact required
caps. Also, even when state have all required capabilities, there could
be state with lower power that still has all required capabilities.
Code is changed to implement above claims.
