The background is that this is used only on some of the older
MSM SoCs, while the newer ones use the arch timer.

We decided to remove the SoC-specific top-level options from
mach-msm as they are becoming rather meaningless these days
and just a burden to maintain at the rate that new variants
get released, so being able to turn off this driver helps make
the kernel slightly smaller if you are building a kernel for
only the more recent models.
