ARM: mvebu: Fix pmsu compilation when ARMv6 is selected
When compiling for multiplatform for both ARMv6 and ARMv7, the default compiler
flags are for ARMv6, and we will get:
/tmp/ccwDEzd0.s: Assembler messages:
/tmp/ccwDEzd0.s:639: Error: selected processor does not support ARM mode `isb '
/tmp/ccwDEzd0.s:645: Error: selected processor does not support ARM mode `isb '
/tmp/ccwDEzd0.s:646: Error: selected processor does not support ARM mode `dsb '
/tmp/ccwDEzd0.s:695: Error: selected processor does not support ARM mode `isb '
make[1]: *** [arch/arm/mach-mvebu/pmsu.o] Error 1
Fix this in a similar manner than done previously in commit
72533b77d30c2be02672e26b5dde1263d7b4c2be, by specifying ARMv7 flags for pmsu.o.
