ARM: pxa: fix building with clang
The integrated assembler in clang does not understand the xscale
specific mra/mar instructions:
arch/arm/mach-pxa/pxa27x.c:136:15: error: unsupported architectural extension: xscale
asm volatile(".arch_extension xscale\n\t"
arch/arm/mach-pxa/pxa27x.c:136:40: error: invalid instruction, did you mean: mcr, mla, mrc, mrs, msr?
mra r2, r3, acc0
Since these are coprocessor features, the same can be expressed using
mrrc/mcrr, so use that for builds with IAS.
