This patch adds a new panic screen, with a QR code and the kmsg data
embedded.
If DRM_PANIC_SCREEN_QR_CODE_URL is set, then the kmsg data will be
compressed with zlib and encoded as a numerical segment, and appended
to the URL as a URL parameter. This allows to save space, and put
about ~7500 bytes of kmsg data, in a V40 QR code.
Linux distributions can customize the URL, and put a web frontend to
directly open a bug report with the kmsg data.

Otherwise the kmsg data will be encoded as a binary segment (ie raw
ascii) and only a maximum of 2953 bytes of kmsg data will be
available in the QR code.

You can also limit the QR code size with DRM_PANIC_SCREEN_QR_VERSION.

Now that fbcon has the skip_panic option, there is no more conflicts
between drm_panic and fbcon.
Remove the build time dependency, so they can be both enabled.

In commit 50c1a36f594b ("drm/gpuvm: track/lock/validate external/evicted

Kconfig for DRM_GPUVM, fix this.

The exynos-next pull is based on a newer -rc than drm-next. hence
backmerge first to make sure the unrelated conflicts we accumulated
don't end up randomly in the exynos merge pull, but are separated out.

Conflicts are all benign: Adjacent changes in amdgpu and fbdev-dma
code, and cherry-pick conflict in xe.

DRM core code cannot call into DRM helper code, as this would lead to
circular references in the modular case.  Hence drop the selection of
DRM_KMS_HELPER.  It was unused anyway, as v10 switched from using
the DRM format helpers to its own color format conversion, cfr. commit
9544309775c3 ("drm/panic: Add support for color format conversion").

Remove the unneeded include of <drm/drm_format_helper.h>.
