drm/amd/display: Only one display lights up while using MST hub
[Why] With the addition of dc_lock acquire before dc_link_handle_hpd_rx_irq, there will be a deadlock situation where commit state sends a request for payload allocation on MST and wait for HPD to process DOWN_REP. [How] Move forward the MST message handling in handle_hpd_rx_irq so that it will not rely on call to dc_link_handle_hpd_rx_irq. Signed-off-by:Qingqing Zhuo <qingqing.zhuo@amd.com> Reviewed-by:
