5f9d3036a6 gpu: nvgpu: Move HAL units to hal/
Move bus related HAL code to new top level HAL directory: hal/.

This directory should mirror the common directory as much as
possible.

There's some nice pros here:

  1. Isolate HAL and common code.
  2. Since the common directory should not be including HAL
     related headers directly this structure will make it
     easier to catch these sorts of bugs with a script.

gm20b & gp10b still uses older ACR interfaces & not yet
moved to Tegra ACR, blob_construct_v0 file can be deleted
once gm20b/gp10b uses Tegra ACR ucode & point to
blob_construct_v1 with simple change.

As ACR ucode can execute on different engine falcon &
should not be dependent on specific engine falcon, used
generic falcon functions/interface to support ACR & doesn't
access any engine h/w registers directly, and files with
chip name has configuration needed for ACR HS ucode & LS
falcons.

fe27a7f934 gpu: nvgpu: add gr/ctx and gr/subctx APIs to set hwpm ctxsw mode
gr_gk20a_update_hwpm_ctxsw_mode() right now validates the incoming
hwpm mode, checks if it is already set, and if not, it will go ahead
and set the new hwpm mode by calling g->ops.gr.ctxsw_prog HALs

Instead of programming hwpm mode in gr_gk20a.c, move the programming
to gr/ctx and gr/subctx units by adding below APIs
nvgpu_gr_ctx_prepare_hwpm_mode() - validate the incoming mode and
                                   check if it is already set
nvgpu_gr_ctx_set_hwpm_mode() - set pm mode in graphics context
nvgpu_gr_subctx_set_hwpm_mode() - set pm mode in subcontext

Add gpu_va field to struct pm_ctx_desc to store the gpu_va to be
programmed into context

Rename NVGPU_DBG_HWPM_CTXSW_MODE_* to NVGPU_GR_CTX_HWPM_CTXSW_MODE_*
and move them to gr/ctx.h

Remove below HALs since they are no longer used
g->ops.gr.ctxsw_prog.set_pm_mode_no_ctxsw()

49506f257e gpu: nvgpu: split update_runlist HAL API in two
A comment for gk20a_fifo_update_runlist() says:

 /* add/remove a channel from runlist
    special cases below: runlist->active_channels will NOT be changed.
    (ch == NULL && !add) means remove all active channels from runlist.
    (ch == NULL &&  add) means restore all active channels on runlist. */

Those special cases call for a new function, so add that. Delete the
update_runlist HAL op and add update_for_channel (like update_runlist
without the special cases) and reload (no channel to add or remove, just
the special cases).

While at it, rename gk20a_fifo_update_runlist_ids to
nvgpu_runlist_reload_ids. It's common across chips and does what the
reload HAL does but for a list of several IDs.

5efc446a06 gpu: nvgpu: make all falcons struct nvgpu_falcon*
With intention to make falcon header free of private data we are making
all falcon struct members (pmu.flcn, sec2.flcn, fecs_flcn, gpccs_flcn,
nvdec_flcn, minion_flcn, gsp_flcn) in the gk20a, pointers to struct
nvgpu_falcon. Falcon structures are allocated/deallocated by
falcon_sw_init & _free respectively.

While at it, remove duplicate gk20a.pmu_flcn and gk20a.sec2_flcn,
refactor flcn_id assignment and introduce falcon_hal_sw_free.
