drm/msm/dp: move mode setup into msm_dp_panel_init_panel_info()
The display layer directly assigns msm_dp_panel mode fields (bpp,
sync polarity, yuv420 flag) instead of letting the panel manage its
own state. Pass adjusted_mode and bpp as parameters to
msm_dp_panel_init_panel_info() and move the assignments inside it.
