drm/msm/dp: force link training for display resolution change
During display resolution changes display have to be disabled first followed by display enable with new resolution. This patch force main link always be retrained during display enable procedure to simplify implementation instead of manually kicking of irq_hpd handle. Changes in v2: -- set force_link_train flag on DP only (is_edp == false) Signed-off-by: Kuogee Hsieh <quic_khsieh@quicinc.com>
