Add following changes.
Fix switch case
latest compiler throwing error where CASE statement does
not have break or return under all the execution paths.
Rename size_add to size_add_
There is a name collision between this one and one coming from
overflow.h. Hence renaming it.
Modify IRQ handling for qce50 module
Change PDE_DATA to pde_data

Currently, there is no lock held when doing crypto
housekeeping when a timeout occurs. Use a lock in this
scenario to avoid concurrent scenario timing errors.

1. When invoke thread have resumed from freezing to running or is
killed, the interruption signals will always interrupt the
smcinvoke callback calls. this will lead the QTEE and listener
to be out of sync.
2. To fix this issue, we remove the signal interruption, this solution
will prevent the smcinvoke from being out of sync.

Since TZ already votes at nominal, voting at nominal from
HLOS will cause aggregate to cross Turbo, so vote at lowSVS

Because the device node of smcinvoke is published at the
beginning of the smcinvoke_probe(), the device node will
be ready while the smcinvoke is not initialized completely.
Hence the smcinvoke_release probably is called when the
smcinvoke driver is not ready. this case will lead to
smcinvoke crash issue.
To avoid this concurrency issue, we create the device node
at the end of the smcinvoke_probe.

1. When there is a large shambridge memory which is not
deleted in time, The shambridge in QTEE might be out of
memory. we met this issue in the TVM TUI unit test.
TrustedUISampleTest -vm --gtest_filter=*Basic_TUIStartStop*
2. To avoid being out of shambridge memory, we should postpone
the deletion of shambridge created by smcinvoke itself.

1.When the QTEE is busy with a high concurrency, the objects and shared
memory bridge will not be released and deleted in time, this will lead
to memory leakage issues in the QTEE.
2.To avoid the memory leakage in case of EBUSY, we add 2 exclusive worker
threads to postprocess the object release and shmbridge deletion
separately.

With the offload implementation, there are a couple of issues
for non-offload usecases.
1. Set config and offload op parameters correctly for non-cipher
usecases.
2. Due to default wait value, there is a crypto operation irrespective
of previous errors, fix that.

1. Currently, each request api sometimes returns 0 even
when an error has occured. This will result in unecessary
crypto requests when failures are expected.
2. The request callback handlers does not check handles to
be NULL before accessing. Fix to add NULL handling.

1. There is no need to vote for high bandwidth for every
ioctl operation, Instead, vote only when a new device
node is opened (which translates to a new session from
a userspace point of view).
2. Fix the way BAM pipes are reset when there is a crypto
operation by initializing it correctly through the SPS
BAM framework.
3. Checking crypto status for every request is performance
heavy. Remove these checks and read status only on
error conditions.

When non-pattern tests are run after pattern tests, there is
stale data from previous tests that never get erased, which
depending on crypto behavior might cause decrypt discrepancies.
Make the change to correctly set the pattern info to the
command descriptors.
Also, convert all debug logs to pr_info to avoid flooding serial
when QCE_DEBUG is enabled.
