gpu: nvgpu: remove ltc_common.c

Remove ltc_common.c and integrate the included functions
into device specific ltc_gXXXX.c files. Merge non-device reg
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.
