        src/sys/arch/aarch64/include: armreg.h

Log Message:
Workaround A-008585 errata in GTMR.

Register reads and writes may provide unstable results if the counter
hardware is active at the same time. This results in non-monotonic
counters seen by both the gtmr interrupt and time counter.

The loops are currently applied unconditionally, restricting them to
appropiate FDT markers can be applied later.
