[PATCH 0/7] nouveau: assorted display fixes (GB20x, r570 DP_CONFIG_STREAM, HF-EEODB EDIDs)

Several fixes for GSP-driven displays consisting of four independent
groups. These were created as part of ongoing HDMI 2.1 and display
handling clean-up work, so some of them are not issues now (e.g., the
2.147GHz pixel clock cap) but fixing them is required to get advanced
features such as FRL, DSC, VRR, etc working properly.

Patches 1-3 fix HDMI infoframes on GB20x. Blackwell removed the legacy
SF vendor-infoframe and GCP packet registers, so the MMIO writes land on
dead or moved offsets. Patch 1 adds a vendor infoframe writer for the new
layout, patch 2 switches GB20x over to it, and patch 3 corrects the GCP
AVMute offsets.

Patch 4 fixes DP modesets on r570 firmware. r570 shrank
NV0073_CTRL_CMD_DP_CONFIG_STREAM_PARAMS, so every call built against the
r535 struct is sent with a wrong paramsSize. Route the .sst/.vcpi paths
through per-version RM API hooks built against each firmware's struct.

Patch 5 fixes vblank interrupts on GB20x. The vblank enable moved to a
second top level FE interrupt enable and fires on a separate low-latency
vector that also needs a retrigger write. Without both, heads don't
report vblanks.

Patch 6 fixes pixel clocks above 2.147GHz on GB20x.
HEAD_SET_PIXEL_CLOCK_FREQUENCY carries 31 bits of Hz, and the CA7D class
adds FREQUENCY_HI for the upper bits. Program it instead of truncating
the clock.

Patch 7 converts nouveau's EDID handling to struct drm_edid, reading
through drm_edid_read_custom() on the GSP path. HDMI 2.1 sinks that
declare their real extension-block count through the EEODB no longer have
their EDIDs truncated to the base block's count.
