The fuse function tegra_get_sku_id() does not exist in upstream and so
when building downstream drivers against an upstream kernel, the build
fails. The tegra_get_sku_id() calls the function tegra_fuse_readl()
which is supported in upstream and exported so can be used by external
kernel modules. The implementation of the tegra_get_sku_id() has been
moved to the header file 'fuse-helpers.h' that can be used by drivers
and allow drivers to be built as external modules. Therefore, migrate
drivers to use this implementation so we can move the implementation
from the downstream kernel.

The NVDLA driver uses the nvhost_err() and nvhost_dbg_fn() macros which
simply call dev_err() and dev_info(), respectively. When compiling the
NVDLA driver against an upstream Linux kernel, nvhost_err() and
nvhost_dbg_fn() are not found and compilation fails. Fix this by
replacing nvhost_err() with either dev_err() or pr_err() and replace
nvhost_dbg_fn() with nvdla_dbg_fn().

The differences between sync_fence ("android sync")
and dma_fence are abstracted away by nvhost in the
nvhost_fence interface. So this change removes use
of sync_fence APIs and replaces them with nvhost_fence
APIs. The nvhost_fence APIs will further either call
sync_fence APIs or dma_fence APIs for given config.
The sync_fence APIs from android staging branch is now
moved to kernel so this change removes header from
android staging branch.

This issue mostly seen in T210 when resource policy for modules are set to
RESOURCE_PER_DEVICE and test with kernel_submit regression, Then it generally
leads to a crash in second or forthcoming iteration of kernel_submit.
Observation:
After completion of channel's job, module gets suspended without freeing the
channel, And when module resume, it's start submiting job on the channel's
syncpoint which is already freed by others.
This scenario occurs in two cases with VIC module,
1 A user application(Ex: nvgpu) freed the syncpoint and VIC module is
in suspend, Now when module will resume it will expect same syncpt
active and belongs to it.
2 In between of 1st possibility If other module(Ex: nvenc) gets the
syncpoint from free list when the first module(VIC) is suspended,
Now when first module(VIC) resume and start submiting job on the same
syncpoint which is already acquired by other module.
Changes made :
o Now, Channel will be freed on channel dma completion
o Channel will be re-acquire on every submit
o Syncpoint will not be freed when channel gets free.
o Syncpoint will be acquire once by user space and will be
freed when use space release the device
o Now, Syncpoints gets mark used and unused using chid
o Set resource policy to RESOURCE_PER_DEVICE for msenc, nvdec,
nvjpg and vic

* Make Kconfig symbols that are not the root GRHOST symbol
bool rather than tristate.
* Update most references to config symbols to use
IS_ENABLED rather than defined.

- On device node close, nvhost ACM updates clock rate
to default rate.
- DLA default rate is set to UINT_MAX.
- These causes max rate requests from DLA on device node close.
Fix,
- Set default rate for DLA as zero. On device node close, aggregrate
requests capped.
- On device node open, keep EMC requests to max.
so DLA inference doesn't impact for perf.
