Remove dependency for nvgpu to invoke devfreq govenor on every

track GPU load (busy vs idle) in software. However, since we currently
read the load GPU from HW/PMU there is no need to invoke the devfreq
governor in this path. Instead it can use timer-based polling.

Remove ltc_common.c and integrate the included functions

definition dependent ltc functions into ltc_gk20a.c/h.
Prior to this patch, ltc_common.c was being directly included
into the device specific ltc source files as a workaround to
allow different devices to share the same code but still include
in different hw reg definitions.
Given that this approach was not adopted for other
systems, this code has been separated out for readability and
consistency.
