The following upstream commits have been back-ported to the out-of-tree
Tegra DRM driver to align with upstream to help pull in the latest
updates from upstream.
Changes from Linux v6.2:
7ad4384d53c6 drm/tegra: Add missing clk_disable_unprepare() in
tegra_dc_probe()
Changes from Linux v6.3:
3fb1f62f80a1 drm/fb-helper: Remove drm_fb_helper_unprepare() from
drm_fb_helper_fini()
Changes from Linux v6.4:
71ec16f45ef8 drm/tegra: Implement fbdev emulation as in-kernel client
25dda38e0b07 drm/tegra: Initialize fbdev DRM client
1ac45068af9d drm/tegra: Hide fbdev support behind config option
08263e91f260 drm/tegra: Removed fb from struct tegra_fbdev
434434608a91 drm/tegra: Remove struct tegra_fbdev
dc06f4a495df drm/tegra: Include <linux/i2c.h>
f68b63ebc433 drm/tegra: Include <linux/of.h>
437405403ab4 drm/tegra: rgb: Make tegra_dc_rgb_remove() return void
The changes have been back-ported to ensure that they build for all
kernel versions supported and utilise conftest as necessary to handle
kernel differences.

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.

- HWPM driver to profile OFA, VIC and NVENC IPs. Hence
add the IP-HWPM registration mechanism.
- Power management is not implemented as IPs are expected
to stay powered on as long as Guest-OS-0 stays powered on.
- Register operations for Read, Write to be handled by exposing
IP Perfmuxes within the hypervisor.

Add support for the optical flow accelerator. Implementation is the
same as for other Falcons except that we omit some legacy things
since the engine only exists from T234 onwards, and the addition
of having to initialize the OFA's safety RAM before boot.

Trivial clean-up for building Tegra DRM 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. Move the header file 'tegra_drm_next.h' under the Tegra DRM source
directory so that we don't need to pass the path for finding the
header when building Tegra DRM as an external module.
3. Remove the 'CONFIG_DRM_TEGRA_NEXT' variable because we always build
Tegra DRM as a module.

Add the upstream tegra-drm driver with the 'Host1x/Tegra UAPI' series
[0] applied. This driver will be built as an external module for testing
and development with 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. Always enable the tegra_drm_ioctl_xxx in the tegra_drm_ioctls and
remove the dependency on CONFIG_DRM_TEGRA_STAGING.
3. Rename the include/uapi/drm/tegra_drm.h to
include/uapi/drm/tegra_drm_next.h to avoid conflicts with upstream
headers when building as an external module.
5. Rename the module that is built to be tegra-drm-next.ko instead of
tegra-drm.ko to avoid any depmod conflicts with the upstream driver.
