[PATCH 30/33] Staging: rt2870: add Antenna Diversity support

[Bartlomiej Zolnierkiewicz]

From: Bartlomiej Zolnierkiewicz <bzolnier@xxxxxxxxx>
Subject: [PATCH] Staging: rt2870: add Antenna Diversity support

rt3070:
* remove non-working AntDiversity config parameter
* remove unused bRxAntDiversity field from COMMON_CONFIG

rt2870:
* propagate Antenna Diversity support from rt3070

Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@xxxxxxxxx>
