The OOT variants of the host1x and tegra-drm drivers originally had
a '-next' suffix in the name to differentiate these from the upstream
versions. Now that the OOT drivers are installed under the 'updates'
directory, the '-next' suffix can be dropped because 'kmod' will
prioritise loading the variant in 'updates' over those built from the
kernel tree.

Add API for reading the activity monitor average count for VIC,
NVENC, and NVDEC. There is currently no support for initializing
actmon, so this relies on someone else on a virtualized system
having initialized it (and mapped the actmon region read-only).

Trivial clean-up for building Host1x by ...
1. Removing the Kconfig file because this is not needed for building
as an external module and we only plan to build this as an external
module.
2. Moving both 'host1x-next.h' header files under the Host1x source
directory so that we don't need to pass the path for finding the
header when building Host1x as an external module.
3. Remove the 'CONFIG_TEGRA_HOST1X_NEXT' variable because we always
build Host1x as a module.

Add the upstream host1x driver with the 'Host1x/Tegra UAPI' series [0]
applied. This driver will be built as an external module for use with
the NVGPU driver on upstream Linux kernels.
The following modifications have been made to the series posted upstream
1. Update the Makefile to always build the driver as a module
2. Remove the tests to see if CONFIG_DRM_TEGRA_STAGING is enabled
3. Rename the include/linux/host1x.h to include/linux/host1x-next.h to
avoid conflicts with upstream headers when building as an external
module.
4. Rename the include/uapi/linux/host1x.h to
include/uapi/linux/host1x-next.h to avoid conflicts with upstream
headers when building as an external module.
5. Rename the module that is built to be host1x-next.ko instead of
host1x.ko to avoid any depmod conflicts with the upstream driver.

Add all the hardware accessors for T186
(channel, sync, uclass accessors)
Add hardware support files for host1x channel,
syncpoints, cdma, pushbuffer, interrupt, and debug support
Keep gather filter disabled
Things working with this :
- cdma operations
- basic channel job submit path
- syncpoint support
- syncpoint interrupt mechanism
- debug dump
With this support, below tests pass for VIC client
