[PATCH v3 1/2] ARM: arch_timers: enable the use of the virtual timer

At the moment, the arch_timer driver only uses the physical timer,

which is likely in a virtualized environment. Instead, the virtual
timer is always available.

This patch enables the use of the virtual timer, unless no
interrupt is provided in the DT for it, in which case it falls
back to the physical timer.

Is this a good candidate for static keys? It looks like we make the
decision fairly early and then we're done and have a bunch of if
statements. Maybe its premature optimization though...
