ARM: export default read_current_timer
read_current_timer is used by get_cycles since "ARM: 7538/1: delay:
add registration mechanism for delay timer sources", and get_cycles
can be used by device drivers in loadable modules, so it has to
be exported.
Without this patch, building imote2_defconfig fails with
ERROR: "read_current_timer" [crypto/tcrypt.ko] undefined!
