Enable 64-bit cycle counters on ARMV7a
ARMv7a has support for returning 64 bits of cycle information by
using two 32-bit registers. However, unless user-space access has
been enabled in the kernel they will return 0. We enable their usage,
but will still return that there is no support in GROMACS if they
are not enabled in the kernel.
