Dom Cobley 9998522074 drm/vc4: crtc: Reduce PV fifo threshold on hvs4 ...

[ Upstream commit eb9dfdd1ed40357b99a4201c8534c58c562e48c9 ]

Experimentally have found PV on hvs4 reports fifo full
error with expected settings and does not with one less

This appears as:
[drm:drm_atomic_helper_wait_for_flip_done] *ERROR* [CRTC:82:crtc-3] flip_done timed out

with bit 10 of PV_STAT set "HVS driving pixels when the PV FIFO is full"
