Second, we add support to handle multiple app load & unload. Media
server is associated with multiple apps on TZ-side. Unloading a single
app for clean up is not enough. QSEECOM needs to handle the app load
& unload of multiple apps associated with the client. During app_load
& app_unload along with app_id, app_name should also be checked.
Besides, keymaster will not be unloaded and app search execution during
app unloading is optimized.
Third, keymaster app has two names with different length: "keymaster" and
"keymaste". To compare the app names correctly, the shorter name length
is choosen for memcmp in __qseecom_send_cmd.

Whenever an async read command is issued to dsp when
the driver is not enabled, there is a crash in userspace.
The read command is disallowed in the driver and an error
is propagated to userspace which results in the crash.
The driver is re-enabled in a subsequent asynchronous write
command anyway, so the async read command can be allowed.
Ensure that read is allowed by removing a superfluous check.

The LiQUID dock driver might probe and attempt to add/remove

Though not fatal, this could lead to the hub ports not being
functional when booting up initially docked. Instead, make
sure USB host controller is ready first by deferring probe
until its driver is present.

The MSM8994 LiQUID docking station does not have a
pin for a dock_enable GPIO, as the USB and Ethernet
ports are always powered via the DC source. Make
this GPIO optional.
As the power to the hub and Ethernet ports may now
be always-on, also make sure to assert the reset lines
prior to adding the USB host controller. This way the
deassertion of the resets will happen after the USB
stack is fully initialized to kick off enumeration.

qseecom.cumulative_mode is used to track the cummulative bus request
mode from all concurrent running clients. It is registered before
send_cmd operation, but is not un-registered after it is complete.
This may cause the bus bandwidth is restored to a wrong mode after
resuming from sleep. Thus, we make change to update it accordingly.
qseecom.current_mode is also updated in suspend/resume function to
ensure timer can scale down bus bw after resume when cumulative_mode
is non-zero. Besides, timer operation is optimized in case there are
multiple unserialized concurrent users of the same timer.
