Add new unit common/gr/global_ctx.c to manage GR global context buffers
This unit provides interfaces to allocate/free/map/unmap all the global
context buffers. It also provides APIs to get/set size of the buffers,
and to get memory handle of the buffers
Use interfaces exposed by this unit instead of directly accessing global
context buffers in common code
Add new header file include/nvgpu/gr/global_ctx.h to declare all the
interfaces.
Rename "struct gr_ctx_buffer_desc" to "struct nvgpu_gr_global_ctx_buffer_desc"
which holds all data for each global context
Remove void *priv since it is no longer used
Add size to the desc structure to store the requested size
Remove global_ctx_buffer_size from struct nvgpu_gr_ctx since it is no longer
used for any real purpose

The device_info table is an array of registers which contain engine
specific data for engines like CE, graphics, nvdec, ioctrl etc.
These registers contain data like intr_enum, reset_enum, pri_base
and so on. The Top unit would include HAL to parse this table and
get data for a particular engine.
Some engines like CE have multiple entries in the device_info table
corresponding to each instance of the engine. Prior to Pascal, each
instance of an engine was denoted by different engine type.
For example in GM20B, there are engine types like COPY_ENGINE0,
COPY_ENGINE1 and so on. In Pascal and chips beyond, a new field
called "inst_id" is added and the engine_type is kept the same.
For example in GP10B, all copy engine entries have same engine type
i.e ENGINE_LCE, but different inst_ids. So for Pascal and chips
beyond, add HAL to get number of entries corresponding to an engine
type.The "get_device_info" HAL will parse a specific instance
of the engine using inst_id argument

Split the nvgpu_sgt code out from the nvgpu_mem code. Although the
two chunks of code are related the SGT code is distinct and as
such should be its own unit. To do this a new source file has been
added - nvgpu_sgt.c - which contains all the nvgpu_sgt common APIs.
These are the facade APIs to abstract the actual details of how any
given nvgpu_sgt is actually implemented.
An abstract unit - nvgpu_sgt_os - was also defined. This unit
exists solely for the nvgpu_sgt unit to call so that the OS
specific nvgpu_sgt_os_create_from_mem() API can be moved from the
common nvgpu_sgt unit. Note this also updates the name of what the
OS specific units are expected to call. Common code may still use
the generic nvgpu_sgt_create_from_mem() API.

1) Constructed clk_arb_gp10b.* files which add support for clk_arb
related HALS including the nvgpu_clk_arb_init and nvgpu_clk_arb_cb.
This doesn't have support for debugfs nor the VFUpdateEvent yet and

3) Linux specific support_clk_freq_controller is assigned true in

4) Incremented the clk_arb_worker.put atomic variable during

5) Added the flag clk_arb_events_supported as part of struct
nvgpu_clk_arb. This flag is used to selectively account for the extra
refcounting present in OS specific code i.e.
nvgpu_clk_arb_commit_request_fd. For igpus, the extra refcount is
reduced during nvgpu_clk_arb_release_completion_dev.
