This change will compile and generate qce50 object
only when QCEDEV(QTI Crypto Engine driver) is
compiled.
Test: Nominal, Stress, Adversial and Repetitive Test passed.

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.

Use DTSI values to vote for clocks instead of using
fixed values. This enables to vote for crypto clocks
on a per target basis.

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.

Current wait times for crypto is too high which might cause
concurerency issues for other EEs. Reduce this to what is
required.
Also, reset the offload error for every new IOCTL call.

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.

Add support for HLOS offload data path in the qcedev driver
mainly to support DRM and HDCP usecases.
Changes extend the current driver to support the following.
- Register multiple pipes for different offload usecases.
- Report timer expiry errors back to userspace.
- Support different iv CTR sizes based on userspace input.
- Support new IOCTLS to support encryption, decryption and
copy offload usecases for DRM and HDCP.

smcinvoke: Release lock for non critical region
When entering into non critical region make sure to release the lock and
increase reference for memobj instead of holding the lock and causing
memobj not to be released when third party module using it.
