[PATCH 1/7] rt2x00: Enable PA_PE bits in TX_PIN_CFG according to active band.

[Ivo van Doorn <ivdoorn@gmail.com>]

From: Gertjan van Wingerde <gwingerde@gmail.com>

(split off from the earlier RT35xx patch submitted by Shiang)

There's no point in enabling the PA_PE bits for the bands that we are
not active on.
