If DP is connected, check the DP BW in mode_valid_ctx() to ensure
that DP's link rate supports high-resolution data transmission.

Fixes: f9698f802e50 ("drm/hisilicon/hibmc: Restructuring the header dp_reg.h")
Why?

Sorry, it should be 0ab6ea261c1f ("drm/hisilicon/hibmc: add dp module in hibmc").

Thanks,

ChangeLog:
v3 -> v4:
- Remove the clock check, suggested by Dmitry Baryshkov.
