d2512bd5ee gpu: nvgpu: create common.fbp unit
create a new unit common.fbp which initializes fbp support and provides
APIs to retrieve fbp data.

Create private header with below data
struct nvgpu_fbp {
        u32 num_fbps;
        u32 max_fbps_count;
        u32 fbp_en_mask;
        u32 *fbp_rop_l2_en_mask;
};

Expose below public APIs to initialize/remove fbp support:
nvgpu_fbp_init_support()
nvgpu_fbp_remove_support()
vgpu_fbp_init_support() for vGPU

Expose below APIs to retrieve fbp data
nvgpu_fbp_get_num_fbps()
nvgpu_fbp_get_max_fbps_count()
nvgpu_fbp_get_fbp_en_mask()
nvgpu_fbp_get_rop_l2_en_mask()

Use above APIs to retrieve fbp data in all the code.

Remove corresponding fields from struct nvgpu_gr since they are no
longer referred from that structure

Removed unused struct from gr_gk20a.h
Change static allocation for struct gr_gk20a to dynamic type.
Change all the files that being affected by that change.

Call gr allocation from corresponding init_support functions, which
are part of the probe functions.
nvgpu_pci_init_support in pci.c
vgpu_init_support in vgpu_linux.c
gk20a_init_support in module.c

Call gr free before the gk20a free call in nvgpu_free_gk20a.

Rename struct gr_gk20a to struct nvgpu_gr

3a764030b1 gpu: nvgpu: Add new mm HAL and move cache code to that HAL
Add a new MM HAL directory to contain all MM related HAL units.
As part of this change add cache unit to the MM HAL. This contains
several related fixes:

1. Move the cache code in gk20a/mm_gk20a.c and gv11b/mm_gv11b.c to
   the new cache HAL. Update makefiles and header includes to take
   this into account. Also rename gk20a_{read,write}l() to their
   nvgpu_ variants.

2. Update the MM gops: move the cache related functions to the new
   cache HAL and update all calls to this HAL to reflect the new
   name.

3. Update some direct calls to gk20a MM cache ops to pass through
   the HAL instead.

4. Update the unit tests for various MM related things to use the
   new MM HAL locations.

This change accomplishes two architecture design goals. Firstly it
removes a multiple HW include from mm_gk20a.c (the flush HW header).
Secondly it moves code from the gk20a/ and gv11b/ directories into
more proper locations under hal/.

9346b104d4 gpu: nvgpu: ltc: create sub-unit for ltc intr
Created sub-unit for ltc interrupt handling.
Following 2-hals are moved from ltc to ltc intr unit:
void (*isr)(struct gk20a *g, u32 ltc);
void (*en_illegal_compstat)(struct gk20a *g, bool enable)

Added new hal in ltc intr sub-unit for configuring ltc interrupts:
void (*configure)(struct gk20a *g);

Moved ltc interrupt related code from ltc to ltc intr unit.
Chip ltc.intr hals are populated with updated function names
created in ltc intr unit.

Converted all "unsigned int" usage to "u32" in ltc and ltc intr units
to match with hardware 32 bit register read/write.

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.
