Subject: drm/msm/dp: make dp_bridge_mode_valid() more precise
Git-commit: 3bcecf2b6d06f71ce3392cc5f5a2d8cd52bd72a1
Patch-mainline: v6.0-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225 jsc#PED-2849

Make dp_connector_mode_valid() return precise MODE_CLOCK_HIGH rather
than generic MODE_BAD in case the mode clock is higher than
DP_MAX_PIXEL_CLK_KHZ (675 MHz).
