media: aspeed: fix mode-detect always time out at 2nd run
[ Upstream commit
62cea52ad4bead0ae4be2cfe1142eb0aae0e9fbd ]
aspeed_video_get_resolution() will try to do res-detect again if the
timing got in last try is invalid. But it will always time out because
VE_SEQ_CTRL_TRIG_MODE_DET is only cleared after 1st mode-detect.
To fix the problem, just clear VE_SEQ_CTRL_TRIG_MODE_DET before setting
it in aspeed_video_enable_mode_detect().
