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 in the qcedev driver to detect KEY_PAUSE
error conditions and report accordingly to userspace.

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.
