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