Subject: [PATCH 5.15 16/32] drm/panel: simple: Fix Innolux G070Y2-L01 BPP settings

From: Marek Vasut <marex@...x.de>

[ Upstream commit fc1b6ef7bfb3d1d4df868b1c3e0480cacda6cd81 ]

The Innolux G070Y2-L01 supports two modes of operation:
1) FRC=Low/NC ... MEDIA_BUS_FMT_RGB666_1X7X3_SPWG ... BPP=6
2) FRC=High ..... MEDIA_BUS_FMT_RGB888_1X7X4_SPWG ... BPP=8

Currently the panel description mixes both, BPP from 1) and bus
format from 2), which triggers a warning at panel-simple.c:615.

Pick the later, set bpp=8, fix the warning.
