gpu: nvgpu: PMU super surface support

- Added ops "pmu.alloc_super_surface" to create
  memory space for pmu super surface
- Defined method nvgpu_pmu_sysmem_surface_alloc()
  to allocate pmu super surface memory & assigned
  to "pmu.alloc_super_surface" for gv100
- "pmu.alloc_super_surface" set to NULL for gp106
- Memory space of size "struct nv_pmu_super_surface"
  is allocated during pmu sw init setup if
  "pmu.alloc_super_surface" is not NULL &
  free if error occur.
- Added ops "pmu_ver.config_pmu_cmdline_args_super_surface"
  to describe PMU super surface details to PMU ucode
  as part of pmu command line args command if
  "pmu.alloc_super_surface" is not NULL.
- Updated pmu_cmdline_args_v6 to include member
  "struct flcn_mem_desc_v0 super_surface"
- Free allocated memory for PMU super surface in
  nvgpu_remove_pmu_support() method
- Added "struct nvgpu_mem super_surface_buf" to "nvgpu_pmu" struct
- Created header file "gpmu_super_surf_if.h" to include interface
  about pmu super surface, added "struct nv_pmu_super_surface"
  to hold super surface members along with rsvd[x] dummy space
  to sync members offset with PMU super surface members.
