Add initialisation for Memory Accessibility Attribute Registers. Generic code cannot know the platform-specific requirements with regards to speculative accesses, so it simply calls a platform_maar_init function which platforms with MAARs are expected to implement by calling the provided write_maar_pair function & returning the number of MAAR pairs used. A weak default implementation will simply use no MAAR pairs. Any present but unused MAAR pairs are then marked invalid, effectively disabling them. The end result of this patch is that MAARs are all marked invalid, until platforms implement the platform_maar_init function.
