Update the host1x driver to align with the latest upstream host1x
driver from Linux v5.19-rc1. Please note that the context bus support
is not included, because this needs to be built into the kernel.

Syncpoint interrupts are not working as expected on Tegra194. The
problem is that the syncpoint interrupt threshold being used is the
global interrupt threshold and not the virtual interrupt threshold.
Fix this by using the virtual interrupt threshold which aligns with
downstream.

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.

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
