wl12xx: remove rx filtering stuff 

The new fw doesn't support rx_filtering configuration (as a
stand-alone command. the rx filtering is done automatically
according to the active role).

* RX Config Options Table
* Bit Definition

* 13 Copy RX Status - when set, write three receive status words
* to top of rx'd MPDUs.
* When cleared, do not write three status words (added rev 1.5)
* 12 Reserved
* 11 RX Complete upon FCS error - when set, give rx complete
* interrupt for FCS errors, after the rx filtering, e.g. unicast
* frames not to us with FCS error will not generate an interrupt.
* 10 SSID Filter Enable - When set, the WiLink discards all beacon,
* probe request, and probe response frames with an SSID that does
* not match the SSID specified by the host in the START/JOIN
* command.
* When clear, the WiLink receives frames with any SSID.
* 9 Broadcast Filter Enable - When set, the WiLink discards all
* broadcast frames. When clear, the WiLink receives all received
* broadcast frames.
* 8:6 Reserved
* 5 BSSID Filter Enable - When set, the WiLink discards any frames
* with a BSSID that does not match the BSSID specified by the
* host.
* When clear, the WiLink receives frames from any BSSID.
* 4 MAC Addr Filter - When set, the WiLink discards any frames
* with a destination address that does not match the MAC address
* of the adaptor.
* When clear, the WiLink receives frames destined to any MAC
* address.
* 3 Promiscuous - When set, the WiLink receives all valid frames
* (i.e., all frames that pass the FCS check).
* When clear, only frames that pass the other filters specified
* are received.
* 2 FCS - When set, the WiLink includes the FCS with the received
* frame.

* buffer including PHY header.
