[20/70] ARM: pxa: fix PGSR register address calculation

From: Greg KH

2.6.39-stable review patch. If anyone has any objections, please let us know.

------------------

From: Paul Parsons <lost.distance@xxxxxxxxx>

commit beb0c9b056b1c23d2029b46a425362e9ccbeba01 upstream.

The file mfp-pxa2xx.c defines a macro, PGSR(), which translates a gpio
bank number to a PGSR register address. The function pxa2xx_mfp_suspend()
erroneously passed in a gpio number instead of a gpio bank number.
