gpu: nvgpu: Move MC HAL to common

Move implementation of MC HAL to common/mc. Also bump gk20a
implementation to gm20b.

gk20a_mc_boot_0 was used via a HAL, but we have only one possible
implementation. It also has to be anyway called directly to detect
which HALs to assign, so make it a true common function.

mc_gk20a_handle_intr_nonstall was also used only in os/linux/intr.c
so move it there.
