Driver receives interface down/del virtual interface commands from kernel
with rtnl lock held. In driver, these commands will wait for SSR to be
completed. So in this case rtnl lock will be held for long time.
To avoid this, cache the north bound command received during SSR and
execute them in re-initialization sequence.

Since os_if_psoc_trans_wait may sleep on a wait event if there is any
active ongoing transition on driver, psoc or vdevs. Hence move the
os_if_psoc_sync_lock(a spin lock bh) inside sync calback API for psoc
look up such that spin lock is not held before starting the wait on
event. os_if_psoc_sync lock is for psoc look up and not for wait
and hence this fix makes locking fine granular as well.

While the concepts of osif_sync started out as a simple set of APIs, it
ultimately evolved into its own full-fledge code module. While the
per-function documenation is present, high-level documentation for the
osif_sync code module as a whole was over looked. Add a high-level
description of the purpose of osif_sync in osif_sync.h

With the recent addition of osif_driver_sync APIs, DSC use is abstracted
behind a common interface. Migrate HDD to the new interface by updating
driver transitions to use the new APIs.

To bring OSIF driver synchronization in line with recent VDEV and PSOC
enhancements, add osif_driver_sync APIs. These allow for atomically
acquiring the driver synchronization context, and protecting various
call flows via DSC primitives.

Rename the osif_*_sync_create_with_trans() to a slightly more
appropriate osid_*_sync_create_and_trans(), to help convey the fact that
the transition does not end when the function returns.

Change I556e9d2833edd2bd26266496b6000347649c5fbe moved hdd_dsc to osif,
