Subject: [PATCH] brcmbca: BCM recommended to handle shutdown event to unload
WLAN driver
WLAN drivers specifically need to be unloaded during soft reboot since
it has separate CPU running.
The sleep is a temporary workaround that was determined experimentally
and will be removed once a proper solution has been provided by
Broadcom.
