Subject: drm/bridge: anx6345: set correct BPC for display_info of connector
Git-commit: 1e8a6ce9186dbf342eebc07cf14cae5e82164e03
Patch-mainline: v5.7-rc3
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Some drivers (e.g. sun4i-drm) need this info to decide whether they
need to enable dithering. Currently driver reports what panel supports
and if panel supports 8 we don't get dithering enabled.
Hardcode BPC to 6 for now since that's the only BPC
that driver supports.
Fixes: 6aa192698089 ("drm/bridge: Add Analogix anx6345 support")
