Existing api msm_pcie_write_reg_field() calls find_next_bit()
and results in a KASAN out of bounds error for taking in
the first parameter by typecasting as unsigned long type.
To avoid the KASAN error use __ffs() instead.

The page used to contain the fuse_dentry_canonical_path to be handled in
fuse_dev_do_write is allocated using __get_free_pages(GFP_KERNEL).
The returned page may contain undefined data, that by chance may be
considered as a valid path name that is not in the cache. In that case,
if the FUSE daemon mistakenly doesn't fill the canonical path buffer,
the FUSE driver may fall into two blocking
request_wait_answer(fuse_dev_write->kern_path->fuse_lookup_name)
causing a deadlock condition.

The context is currently kept alive until all its fences are
released. This means that we do not destroy a context until all
the fence fds associated with it are closed by userspace, which may
be a long time. Instead, remove the timeline's refcount on its
context when it is detached. This permits the context to be freed
once all its fences signal.

Do not include standard key support while creating a keyslot
manager because current implementation does not support standard
keys with hardware key manager. This leads to per file key test
failure, which tries generate standard keys and performs operations
using it. Per file keys should by default use fallback mechanism in
block crypto.
Test: Verified bootup and vts_kernel_encryption_test. Also verified

During mhi resume if mhi detects link down then it posts link
recover event where cnss platform driver goes for self recovery,
as part of recovery the shutdown & powerup sequence is done.
During shutdown the PCIe link is suspended, the link suspend
should be L2 suspend. But in current scenario, it goes for DRV
suspend as the drv_connected_last flag is still set because
resume is initiated by host driver to get qmi stats via
cnss_pci_resume_bus. So on power up the link does not come up
as it tries for DRV resume instead of L2 resume. To fix this,
during shutdown the link suspend should be L2 suspend, so
add code to always do PCIe L2 suspend during shutdown.
