DONT_SLEEP bit in PMU GLobal control register, if set, wakes up the
microblaze from sleep state. This makes the "sleep" instruction
ineffective by making the MB to toggle between sleep and wake states
in the core loop. So this bit is cleared to prevent such a situation
and ensure that MB wakes up only in case of an interrupt event.

Basic APIs are provided for modules to send/receive IPI messages.
These are wrappers around IPI driver functions and are intended to
support a common message structure. Currently only a module's IPI ID
is considered.This can be extended to include checksum and other fields in
IPI message and dispatching IPIs based on module id.

-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
