drm/msm/dp: store mode YUV420 information to be used by rest of DP

Browse Source 
Wide bus is not supported when the mode is YUV420 in DP. In preparation
for changing the DPU programming to reflect this, the value and
assignment location of wide_bus_en for the DP submodules must be
changed. Move it from boot time in dp_init_sub_modules() to run time in
dp_display_mode_set.
