This change increases the max command logging capability.
It also adds cmd log print if pwr ctrl failure detected.
Finally, it changes function name ufshcd_cmd_log_print to
ufshchd_print_cmd_log to align with the naming of other
ufshcd debug print functions.

In newer kernel (msm-4.4 or later), for AEAD ciphering, crypto api has
been re-worked and the assoclen defines the length of association data
and iv together. But for rfc4309(ccm(aes)), iv is not part of AAD.
Therefore, change qcrypto driver to remove the iv, by subtract 8 from
assoclen for rfc4309(ccm(aes)).

Currently the priority and other behavior of a command stream
is provided by the user application during submission and
the application is expected to internally maintain the settings
for each 'context' or 'rendering queue' and specify the correct
ones.
This works okay for simple cases but as applications become more
complex we will want to set context specific flags and do various
permisson checks to allow certain contexts to enable additional
privileges.
Add kernel-side submit queues to be analogous to 'contexts' or
'rendering queues' on the application side. Each file descriptor
instance will maintain its own list of queues. Queues cannot be
shared between file descriptors.
For backwards compatibility context id '0' is defined as a default
context specifying middle priority and no special flags. This is
intended to be the usual configuration for 99% of applications so
that a garden variety application can function correctly without
creating a queue. Only those applications requiring the specific
benefit of different queues need create one.
In addition to the basic infrastructure, allow the user to specify
the queue priority - this will be used in lieu of the legacy
flags to set priority during the submission. Only the master DRM
instance can set the highest priority, but all the others are open
to all processes.

votable to disable delta_bsoc interrupt during probe. However, it
doesn't set the internal variable for votable to not allow a
similar vote again. When a vote is made later to disable the
interrupt again, it can end up in invoking the callback again.
This leads to an unbalanced interrupt disable warning. Fix it.

With the recent 'commit d07d314e7d ("fs/mbcache: fix use after
free issue in mb_cache_shrink_scan()")', the ce entry is deleted
from mbcache list after ce->e_refcnt incremented under global
spinlock mb_cache_spinlock. If __mb_cache_entry_release(), is waiting
for mb_cache_spinlock at the same time, to add the same ce to
mb_cache_lru_list and if it gets the lock after mb_cache_entry_get()
deleted it, then it corrupts the list, as that element will be freed
immediately after mb_cache_entry_get(). When this list is accessed next
time for deleting/adding another ce, we see list corruption issue.
Fix this by synchronizing these two contexts with mb_cache_spinlock and
evaluating the conditions(ce->e_refcnt) in __mb_cache_entry_release()
under the global lock before adding ce to mb_cache_lru_list.
