ARM: Remove unnecessary subpage workarounds
In the ARM per-CPU peripherals (GIC, private timers, SCU, etc), remove workarounds for subpage memory region read/write functions being passed offsets from the start of the page rather than the start of the region. Following commit 5312bd8b3 the masking off of high bits of the address offset is now harmless but unnecessary.
