2af9d5787c gpu: nvgpu: move global pagepool buffer commit hal to hal.gr.init
Move g->ops.gr.commit_global_pagepool() hal to hal.gr.init unit as
g->ops.gr.init.commit_global_pagepool()
Also move g->ops.gr.pagepool_default_size() hal to
g->ops.gr.init.pagepool_default_size()

Add global_ctx boolean flag as parameer to
g->ops.gr.init.commit_global_pagepool() to distinguish between
committing global pagepool v/s ctxsw pagepool buffers

Remove register header accessors from gr_gk20a_commit_global_ctx_buffers()
and move them to hal functions

Move hal definitions to gm20b/gp10b hal files appropriately

Remove g->ops.gr.pagepool_default_size() hal for gv11b since gv11b can
re-use gp10b hal

64269c2c55 gpu: nvgpu: modify init_pbdma_intr_descs into separate HALs
init_pbdma_intr_descs HAL ops is used to update the internal values of
the struct intr within struct fifo_gk20a. Three kinds of
intr_descriptors are filled i.e. device_fatal_0, channel_fatal_0 and
restartable_0. Breaking them into separate HALs has the advantage of
reusing the h/w headers corresponding to the device_fatal_0 as they are
same across all the architectures while those of channel_fatal_0 varies.

Another advantage is to now decouple pbdma from filling in values
within the fifo_gk20a struct. A new method gk20a_fifo_init_pbdma_descs
is constructed that initializes the above intr struct by calling the
separate HAL ops for these.

Earlier falcon HAL ops were embedded in the falcon structure. For clear
separation of common and HAL these ops will have to be accessed through
g->ops.falcon interfaces.
With these changes nvgpu_falcon_* functions directly call falcon gpu
ops functions for falcon. Falcon registers and HAL functions are
exported from falcon_gk20a.h. HAL files per platform are now
updated with base falcon functions.
Falcon software state such as is_falcon_supported, is_interrupt_enabled
and flcn_base are set from software init functions defined per chip.
