staging: brcm80211: Better debug support added to brcmfmac driver

Browse Source 
With the current implementation there is no way to selectively enable
required debug messages, as all the messages are currently under WL_DBG.
With this fix, we are introducing several log levels which will enable
us to print only the required debug messages.
WL_ERR --> Prints error messages
WL_CONN --> Prints all debug messages pertaining to connection
management
WL_SCAN --> Prints all debug messages pertaining to scanning
WL_TRACE --> Prints all trace(Enter/Exit) sequence of cfg80211 calls
WL_INFO --> Prints all informational messages.
By default, only WL_ERR messages are enabled.
