gpu: nvgpu: move ctxsw related data to gr falcon

Browse Source 
Added new function to add require sw initionaltions. before enabling
gr hw. Added nvgpu_netlist_init_ctx_vars and nvgpu_gr_falcon_init_support
as part of this function:
int nvgpu_gr_prepare_sw(struct gk20a *g)

Moved following structure defs from gr_gk20a.h to gr_falcon.h and
renamed appropriately:
gk20a_ctxsw_ucode_segment -> nvgpu_ctxsw_ucode_segment
gk20a_ctxsw_ucode_segments -> nvgpu_ctxsw_ucode_segments

Moved following struct to gr_falcon_priv.h:
gk20a_ctxsw_ucode_info -> nvgpu_ctxsw_ucode_info

Moved following data from struct gk20a to new structure in gr_falcon_priv.h
struct nvgpu_gr_falcon:
struct nvgpu_mutex ctxsw_disable_lock;
int ctxsw_disable_count;
struct gk20a_ctxsw_ucode_info ctxsw_ucode_info;

Also moved following data from gr_gk20.h to struct nvgpu_gr_falcon:
struct nvgpu_mutex fecs_mutex;
bool skip_ucode_init;
wait_ucode_status
GR_IS_UCODE related enums
eUcodeHandshakeInit enums

Now add a pointer to this new data structure from struct gr_gk20a to
access gr_falcon related data and modified code to reflect this
change:
struct nvgpu_gr_falcon *falcon;

Added following functions to access gr_falcon data:
struct nvgpu_mutex *nvgpu_gr_falcon_get_fecs_mutex(
				struct nvgpu_gr_falcon *falcon);
struct nvgpu_ctxsw_ucode_segments *nvgpu_gr_falcon_get_fecs_ucode_segments(
				struct nvgpu_gr_falcon *falcon);
struct nvgpu_ctxsw_ucode_segments *nvgpu_gr_falcon_get_gpccs_ucode_segments(
				struct nvgpu_gr_falcon *falcon);
void *nvgpu_gr_falcon_get_surface_desc_cpu_va(
				struct nvgpu_gr_falcon *falcon);
