gpu: nvgpu: move ltc related data to nvgpu_ltc

Browse Source 
Moved following ltc related data to struct nvgpu_ltc
and has a reference to it from struct gk20a:
  struct nvgpu_spinlock ltc_enabled_lock;
  u32 max_ltc_count;
  u32 ltc_count;
  u32 slices_per_ltc;
  u32 cacheline_size;

Added function remove_support for ltc and it is called
during nvgpu remove sequence.

Added following helper functions in ltc.h:
u32 nvgpu_ltc_get_ltc_count(struct gk20a *g);
u32 nvgpu_ltc_get_slices_per_ltc(struct gk20a *g);
u32 nvgpu_ltc_get_cacheline_size(struct gk20a *g);

Removed redudnant ltc.init_fs_state call from vgpu init
sequence since it is getting called from nvgpu_init_ltc_support.
