Revert "clocksource: arch_timer: Enable user access to the physical counter"



Disable user access to physical counter. This reverts
commit <f1a1ad6d>("clocksource: arch_timer: Enable
user access to the physical counter").

This could potentially break the userspace applications
using physical counters; but all those usages should
move to using virtual counter, to get the timing
information.
