Copy engine(CE) has multiple entries in the device_info table

For example in GM20B, there are engine types like COPY_ENGINE0,

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.

Fifo scheduling APIs require the HW reg mask accessor
fifo_sched_disable_runlist_m() to be used even from high-level logic.
Restructure the APIs to take in an explicit bitmap of runlist IDs and
translate the bitmap to units of fifo_sched_disable_runlist_m() (which
happens to be an identical bitmap) only just before accessing hardware.

Split out the code to check which engines on a particular runlist are
busy from gk20a_fifo_runlist_reset_engines() and make it a HAL op.
Resetting engines is common across chips but status is read from
registers.

The function gk20a_fifo_recover_tsg has to pass a valid struct tsg to
other functions from within. This qualifies it to have a pointer to
struct tsg_gk20a as an input parameter.
Tsg specific parts of the gk20a_fifo_preempt_timeout_rc are now moved
into another function gk20a_fifo_preempt_timeout_rc_tsg
that takes a tsg as an input and passes it to gk20a_fifo_recover_tsg.
The pointer to a tsg is also used to enumerate channels from within.
The function gk20a_fifo_preempt_timeout_rc now contains only channel
specific code.

gv11b_fifo_preempt_tsg needs to access the runlist_id of the tsg as
well as pass the tsg pointer to other public functions such as
gk20a_fifo_disable_tsg_sched. This qualifies the preempt_tsg to use a
pointer to a struct tsg_gk20a instead of just using the tsgid.

replace tsgid with a pointer to a struct tsg_gk20a in the function
gk20a_fifo_tsg_abort(). gk20a_fifo_tsg_abort needs to enumerate through
all the channels within the tsg as well as pass the tsg pointer to
other functions, qualifying the need to use a pointer instead as an
input parameter.

MISRA Rule 10.4 only allows the usage of arithmetic operations on
operands of the same essential type category.
Adding "U" at the end of the integer literals to have same type of
operands when an arithmetic operation is performed.
This fixes violations where an arithmetic operation is performed on
signed and unsigned int types.
