USB: ehci-msm-hsic: Don't mark all IRQs as wakeup capable

Some HSIC core interrupts might not be capable of waking up system
from suspend (or XO shutdown) if they are not routed to MPM.
Marking such IRQs as wakeup capable may prevent system from entering
suspend.

qseecom:  Fix failure to release qseecom handle

qseecom_release() returns a failure, if it is unable to find
app_id of zero, associated with the handle in the app list.

There exists scenarios where the handle may not have the
app_id initialized and remain to be 0.  In these scenarios,
once the uninitialized zero app_id is not found in the list,
it returns a failure.

Fix to this is look for non-zero valid app_id in the app_list when
releasing the handle.

msm: Fix correct topology for qseecom bus scaling.

Currently, bus scaling topology for qseecom is incorrect.
 -Added the correct topology paths for accessing Crypto

 -Removed setting the clock frequency of DFAB. This is
  done by the bus driver.
 -Removed references to the dfab clock instance defined

qseecom: Remove extra call to disable clock.

Currently the qseecom driver calls qsee_disable_clock_vote() in

disabling of the clock and results in turning off the bus clocks
inconsistently.
This change fixes the inconsistency.

qseecom:Fix race condition while voting for clocks

In the current functionality, if DFAB clock is already on and a
request is made to turn on SFPB clock, the DFAB clock is turned
off and SFPB clock is turned on and vice-versa.

The above situation can lead to unexpected errors. The current fix
makes sure that clocks that are on are not voted to be off without
explicit request.

The above is needed for allowing kernel modules to communicate

qseecom: Add support for loading commonlib image

Load the common library image on secure domain during
initialization of the driver.

All secure app loaded on the secure domain (TZ) is currently
refactored to not include all secure libraries. The libraries
are now a part of separate image.  This is used by all secure app.
This common lib image needs to be  loaded before any secure app
can be loaded.

This patch adds support for handling this new change based off
the QSEE version running on secure domain.  The change is to
load the common library image before loading any secure app.

qseecom: Add clk management

The CE clock was initialized to run at max of 100 MHz.  This
was done during the probe call. Running the CE clk at 100 MHz
always, is causing a power regression.

Fix is to enable the clk and set it to run at the nominal level
of 50 MHz.  Further more, add clk gating to ensure CE clks are only
bumped up to the max of 100 MHz when client request for high bandwidth.

QSEE verion 2 supports relocatable images. To support this
a chunk of contiguous memory in the first 256MB  bank is
reserved for loading the secure applications.  The location
and size of this memory region is defined in the device tree
data of the driver.

This patch
- Adds supports for retrieving the address and size of the
  memory region reserved for the secure app from the device
  tree data
- Adds a new command to issue to QSEE for notifying this
  app region information (retrieved from device tree)

qseecom: Fix memory leak when __check_if_app_exist() fail

In qseecom_start_app(), when __check_if_app_exist() returns an
error status, the function is exited  with a -EINVAL error.
This result in not de-allocating memory that was allocated for
the handle prior to calling __check_if_app_exists()

Memory that was allocted for the handle, needs to be de-allocated
before exiting with an error status when __check_if_app_exists()
return a failure.

The fix is to re-order the memory allocation of the handle after
__check_if_app_exists() goes through successfully.

qseecom: Tie performance request to client handle

When a user space client application crashes without
disabling clk vote,  there is a possibiltity of crypto
HW being left at its high bandwidth mode.  This results
in power drain.

This patch ties the performance request to the client
handle.  When any client handle is released (done when
the client handle is closed explicitly or when a client
application crashes), appropriate calls are invoked to
disable clk voting as part of closing the handle
