drivers/bus: arm-cci: fix combined ARMv6+v7 build

When we build a kernel with support for both ARMv6 and ARMv7,
gas is trying to be helpful by pointing out that the arm-cci
driver would not work on ARMv6:

/tmp/ccu1LDeU.s: Assembler messages:
/tmp/ccu1LDeU.s:450: Error: selected processor does not support ARM mode `wfi '
/tmp/ccu1LDeU.s:451: Error: selected processor does not support ARM mode `wfe '
make[4]: *** [drivers/bus/arm-cci.o] Error 1

We know that the driver will only be used on ARMv7, hence we
can annotate the inline assembly listing to allow those instructions.
