Added new gr_config member to hold TPC physical id map.
Updated ecc stats structures to hold physical gpc,tpc
numbers. Previously logical id's were exposed via ecc
sysfs nodes.
Consumers of ecc sysfs nodes refer tpc_fs_mask which is
physical gpc/tpc layout whereas ecc sysfs nodes were updated
with logical gpc/tpc layout. This change ensures that both
use the same framework.

Changes
1. Remove dGPU flag dependency on calling gsp sw init on tot.
2. Created Enable flag for gsp scheduler to enable them on ga10b
platforms.
3. Engine config flag is only enabled for dGPU enabled platforms, as gsp
is using engine functions it need to be enabled for all gsp sched
enabled builds.
4. Changes in gsp_sequence_init/de_init where on qnx we are seeing
issues.

Use CONFIG_KMD_SCHEDULING_WORKER_THREAD instead of
CONFIG_NVS_KMD_BACKEND to remove confusion about the CPU based
KMD scheduling worker thread.
The KMD based scheduling worker thread caters to both Manual Mode
CPU based scheduler as well as Automatic Round Robin CPU based
scheduler.
For the traditional submit path, add correct handling of the
CONFIG_NVS_PRESENT. CPU based worker thread should be part of
CONFIG_NVS_PRESENT. Eventually, when DCONFIG_KMD_SCHEDULING_WORKER_THREAD
is removed, the application must switch to GSP.

If NEXT bit remains set for a channel being unbound, it can lead to
MMU fault of type unbound inst block. When userspace is closing the
channel and NEXT bit is set, userspace retries.
When force killing the channel, nvgpu can retry few iterations to
ensure the channel is truly idle and unbound. If the channel is
really stuck then unbind will fail and TSG will be aborted.

The error injection code was enabled only when CONFIG_NVGPU_DGPU = n
so that the dGPUs do not attempt any error injection callback
function registration. But, this introduced dependency on DGPU
config when needs to be explicitly set to n for error injection to
be enabled.
Remove the dependency by moving the error injection callback
registration and deregistration to a HAL which is enabled only
on GA10b.

GR context associated with channel is updated in various driver paths.
Sequence to do the same is disable the TSG, preempt the TSG, update
the GR context or instance block and then enable the TSG.
These operations and runlist updates for channel have to be done under
TSG specific ctx_init_lock to avoid the race.
suspend_contexts and resume_contexts needs special handling which is
not covered in this patch.
