drm/tegra: Backport fbdev updates

Browse Source 
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.
