clocksource: arm_arch_timer: rename type macros
In preparation for moving the type macros out into a header, rename these so they are namespaced w.r.t. the arch timer. We'll apply the same prefix to other definitions in subsequent patches. This will aid consistency and avoid potential name clahses when this move occurs. No functional change.
