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.

MISRA Rule-17.7 requires the return value of all functions to be used.
Fix is either to use the return value or change the function to return
void. This patch ensures that WARN and WARN_ON always return void; and
introduces a new nvgpu_do_assert construct to trigger the equivalent
of WARN_ON(true) so that stack can be dumped (depends on OS support)

Below HALs to get max FBPs, max LTC per FBP, max LTS pet LTC values are
right now defined by GR unit.
g->ops.gr.get_max_fbps_count()
g->ops.gr.get_max_ltc_per_fbp()
g->ops.gr.get_max_lts_per_ltc()
These HALs only read registers from hw_top_*.h h/w unit, and as such
belong to TOP unit. Move them appropriately as below
g->ops.top.get_max_fbps_count()
g->ops.top.get_max_ltc_per_fbp()
g->ops.top.get_max_lts_per_ltc()
Remove hw_top_*.h h/w header include from gr_gk20a.c and gr_gm20b.c

Rename gv11b/fecs_trace_gv11b.* files to
common/gr/fecs_trace/fecs_trace_gv11b.*
Also move HAL API gk20a_fecs_trace_get_buffer_full_mailbox_val()
to gr/fecs_trace unit and rename it as
gm20b_fecs_trace_get_buffer_full_mailbox_val()
Protect gm20b/gv11b HAL code under CONFIG_GK20A_CTXSW_TRACE
Remove tu104/fecs_trace_tu104.* since tu104 will re-use gv11b HAL
Fix g->ops.fecs_trace.get_buffer_full_mailbox_val() for vgpu/gv11b and
use gv11b HAL
