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.

Update all Kconfig files and Makefiles to rely on the kernel overlay
feature. In particular, don't include any Kconfig files or Makefiles
from other overlays. -I directives in CFLAGS are not yet cleaned up.

t18x repo will be discontinued and all code that
resides there is moved into nvidia/.
So, every reference to t18x/ should be corrected

on project name being the extension.
Makefiles and Kconfig files brought over from
t18x have .t18x suffix.
Changed to .nvidia

Define host1x_dev_ops for T186
Add API load_streamid_regs() to load streamid registers
Set this API to host1x_dev_ops.load_regs so that we
set streamid registers during host1x_probe()
Add a static table which includes streamid mappings
for all the clients

Add host1x05 version and fill in the h/w details
in host1x05_info
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
$nvrm_channel channel_Basic
$nvrm_channel --module=vic
