3267530f22 gpu: nvgpu: Use device_info parsing HAL for Fifo
Update the fifo code to use the HALs exposed by "Top" unit to
read data from device_info table.

The information for GRAPHICS engine in device_info table is
now parsed using the get_device_info HAL from "Top" unit.

Copy engine(CE) has 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
different instances of an engine. 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, we use a different HAL to
get CE information from device_info table.

38f8b3fb00 gpu: nvgpu: Add HALs for device_info table parsing
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

7e68e5c83d gpu: nvgpu: userd slab allocator
We had to force allocation of physically contiguous memory for
USERD in nvlink case, as a channel's USERD address is computed as
an offset from fifo->userd address, and nvlink bypasses SMMU.

With 4096 channels, it can become difficult to allocate 2MB of
physically contiguous sysmem for USERD on a busy system.

PBDMA does not require any sort of packing or contiguous USERD
allocation, as each channel has a direct pointer to that channel's
512B USERD region. When BAR1 is supported we only need the GPU VAs
to be contiguous, to setup the BAR1 inst block.

- Add slab allocator for USERD.
- Slabs are allocated in SYSMEM, using PAGE_SIZE for slab size.
- Contiguous channels share the same page (16 channels per slab).
- ch->userd_mem points to related nvgpu_mem descriptor
- ch->userd_offset is the offset from the beginning of the slab

- Pre-allocate GPU VAs for the whole BAR1
- Add g->ops.mm.bar1_map() method
  - gk20a_mm_bar1_map() uses fixed mapping in BAR1 region
  - vgpu_mm_bar1_map() passes the offset in TEGRA_VGPU_CMD_MAP_BAR1
  - TEGRA_VGPU_CMD_MAP_BAR1 is called for each slab.
