[ARM] 3191/1: Mark I/O pointer as const in __raw_reads[bwl]

Browse Source 
Patch from Deepak Saxena

Mark the ioremap'd cookie/pointer in said functions as const since
we should not be actualy touching the data. This fixes a slew of
compile warnings on IXP4xx as our reads[bwl] already mark this
parameter as const.
