This follows normal Linux convention and is more useful since the new
name will make it apparent which network device the work-queue is for
(e.g., the name will be "wlan0-wq" for network device "wlan0").
hif_workqueue allocation has to move from
cfg80211.c:wilc_cfg80211_init() to netdev.c:wilc_netdev_ifc_init()
because the network device name is not known until after the netdev is
registered. The move also makes sense because netdev.c is already
responsible for destroying the work queue when it is no longer needed.

Use the correct sequence to configure clockless registers for chip wake-up.
The following sequence is expected from WILC chip for wakeup:
- set wakeup bit in wakeup_reg register
- after setting the wakeup bit, read back the clock status bit for wakeup
complete.
For SDIO/SPI modules, the wakeup sequence is the same except uses different
register values so refactored the code to use common function for both
SDIO/SPI bus.

Add new WID(WID_WOWLAN_TRIGGER) to send wake_enable information to firmware.
In 'set_wakeup' cfg80211_ops callback, the enable information was not
passed to firmware which is required to handle WOWLan trigger notification
from firmware.

When the BSS reference holds a valid reference, it is not freed. The 'if'
condition is wrong. Instead of the 'if (bss)' check, the 'if (!bss)' check
is used.
The issue is solved by removing the unnecessary 'if' check because
cfg80211_put_bss() already performs the NULL validation.

Move initialization & deinitialization of 'deinit_lock' mutex lock inside
wlan_init_locks() & wlan_deinit_locks() API's respectively alongside other
locks. After the movement, the client count variable(client_count) which is
used for lock init/deinit is removed.

We used to not require anything in terms of registering netdevs
with cfg80211, using a netdev notifier instead. However, in the
next patch reducing RTNL locking, this causes big problems, and
the simplest way is to just require drivers to do things better.
Change the registration/unregistration semantics to require the
drivers to call cfg80211_(un)register_netdevice() when this is
happening due to a cfg80211 request, i.e. add_virtual_intf() or
del_virtual_intf() (or if it somehow has to happen in any other
cfg80211 callback).
Otherwise, in other contexts, drivers may continue to use the
normal netdev (un)registration functions as usual.
Internally, we still use the netdev notifier and track (by the
new wdev->registered bool) if the wdev had already been added
to cfg80211 or not.

Added multiple queues[BK,BE,VI,VO] to handle different priority data
packets. Before adding a packet to the queue, checked its priority from
the header, and then add to the suitable queue. The limit for each queue
is maintained separately. Also while passing the packets to the firmware
via VMM take care to select data packets based on priority and available
space.
