While running regressions, observed below kernel panic when sdio disconnect
called. This is because of, kthread_stop() is taking care of
wait_for_completion() by default. When wait_for_completion triggered
in kthread_stop and as it was done already, giving kernel panic.
Hence, removing redundant wait_for_completion() from rsi_kill_thread().

Operating mode determines the support for other protocols.
This is made as module parameter for better usage.

BT frames are passed through coex and hal modules to BUS.
After firmware is loaded, based on the operating mode CARD
READY frame comes for each protocol. When BT card ready is
received, BT attach is called.
Protocol operations are exchanged between the modules
at initialization time.
Build flag CONFIG_RSI_COEX is introduced to enable coex support
if CONFIG_BT_RSIHCI is enabled. Coex operations are valid if
coex mode is greater than 1 only.

Rx bluetooth endpoint shall be added in further patches. Rx control
block is introduced here to handle Rx packets properly. Separate
function is written to initialize the RX control blocks.

Some wowlan related code was outside CONFIG_PM flag which caused these
build errors. They are fixed by moving that code under CONFIG_PM flag.

Fixes: ef71ed0608c ("rsi: sdio: Add WOWLAN support for S5 shutdown state")
Fixes: a24e35fcee0 ("rsi: sdio: Add WOWLAN support for S4 hibernate state")

WoWLAN is supported in RS9113 device through GPIO pin2.
wowlan config frame is internally sent to firmware in mac80211
suspend handler. Also beacon miss threshold and keep-alive time
values are increased to avoid un-necessary disconnection with AP.

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

The older firmware loading method is not usable by any Redpine chipset.
Hence removing that part of the code. Older firmware image with
rsi_91x.fw name is deprecated

Since the rsi_create_kthread interface does not include any format
string arguments, make sure that the resulting thread name can never
accidentally process the name as a format string.
