msm: subsystem_restart: Add notification to indicate powerup failure

Currently, if powering on a subsystem during restart fails, a
kernel panic is trigerred immediately.
Instead, send a 'powerup failure' notification to the drivers
that have registered for notifications regarding the subsystem.
The drivers can then do the necessary cleanup/logging before a
kernel panic is triggered.

msm: ssr: Send notification during a cold boot failure

Currently, when powering on a subsystem during cold boot fails,
the drivers that have registered for notifications about the
subsystem are not intimated.
Send the 'powerup failure' notification to these drivers to give
them an opportunity to do the necessary cleanup/logging at their
end before the subsystem is shutdown.

wcnss: Log debug registers when receives certain notification

If powering on a subsystem during restart fails, SSR framework will send
a "powerup failure" notification to the subsystem. Add the support that
WCNSS platform driver will register to listen the notifications and if
receives "powerup failure" notification, it will log the debug registers.

wcnss: add API to check if wcnss is undergoing an SSR

Wlan driver should not read registers from wcnss or
try to communicate with the chip when it is undergoing
a subsystem-restart. Added an API with the wcnss platform
driver to check if ssr is in progress, this API will be
used by the wlan driver to protect register access and
other prohibited operations.

msm: mdss: move MDSS revision macros to /linux/msm_mdp.h

Currently kernel driver and user mode libraries keep their own
copies of HW revision numbers. This strategy is prone to errors
and usually frowned upon. Fix this by moving revision information
to sanitized header which is shared by kernel drivers and user mode
libraries.

msm: kgsl: Add new API's to track device mutex owner

Add new API's kgsl_mutex_lock/unlock to track device mutex owner.
Mutex owner is an atomic variable and all operations set/clear on
it are also atomic to avoid any race conditions.

If a thread tries to acquire the mutex using new API, try to acquire
the mutex only if mutex owner is not same as current thread. This is
to prevent deadlocks which can happen if a thread tries to acquire
mutex with mutex held.
