arm: Clean up m5ops assembly library
The m5ops assembly library contains a lot of repetitive code. This changeset adds two macros, FOREACH_M5OP and FOREACH_M5_ANNOTATION, to m5ops.h that simplify architecture-specific implementations. The ARM and ARMv8 m5op implementations have been updated to use the new macros. Signed-off-by: Andreas Sandberg <andreas.sandberg@arm.com> Reviewed-by: Curtis Dunham <curtis.dunham@arm.com>
