clocksource/drivers/arm_arch_timer: Extract elf_hwcap use to arch-helper
Different mechanisms are used to test and set elf_hwcaps between ARM
and ARM64, this results in the use of ifdeferry in this file when
setting/testing for the EVTSTRM hwcap.
Let's improve readability by extracting this to an arch helper.
