The support sparse HAL severs only one purpose: return true or false
depending on whether the given chip supports sparse mappings. This
HAL is used to, in turn, program (or not) the
NVGPU_SUPPORT_SPARSE_ALLOCS enabled flag. So instead of having all
this rigmarole to program this flag just program it for all native
GPUs. Then, in the vGPU specific characteristics function disable it
explicitly. This seems to have precedent already.

pstate s/w setup needs to know offsets of boardobjs present
in PMU super surface to construct boardobj set/get_status
construct.
With SSMD support, boardobj offset will be part of SSMD
lookup table which is part of PMU super surface buffer &
updated by PMU RTOS during init stage.
As SSMD is updated at init stage & SSMD will be ready for nvgpu
to read offsets only when PMU init message is received,
so pstate s/w must wait till PMU is ready to construct
boardobj set/get_status

Currently, NVGPU must modify RM/PMU defined common super surface

as NVGPU cannot include directly RM/PMU defined struct due to number

gk20a_fifo_update_runlist_locked() and the vgpu counterpart do three
things:
1. find out whether there's a channel to add or remove (if not, the
whole runlist is just reconstructed or cleared),
2. reconstruct the runlist format for hardware (or the vgpu message),
3. actually update the runlist to hw and maybe wait for finish.
Split out the two first operations to separate functions to make the
code easier to understand. Now it's also clearer that the "add"
parameter behaves completely differently depending on whether the
channel pointer is NULL or not.
Also ignore (with a warning) channels not bound to a tsg. We shouldn't
get runlist updates on such channels. This simplifies the control flow a
bit.

Instead of using kmalloc() to get a buffer for storing the
computed flags string during DMA debugging use a stack
buffer. This removes the need for a kmalloc() call. The
problem with kmalloc() is that if a dma_alloc() fails due
to being out of memory the kmalloc may likely fail, too!
Also simplify the logic now that there's no need to do
any error checking for a kmalloc() call.
