Subject: [PATCH 2/2] drm/panel: boe-tv101wum-nl6: Reduce lcm_reset to send initial code time

From: Xinlei Lee <xinlei.lee@...iatek.com>

Since the panel spec stipulates that the time from lcm_reset to DSI to
send the initial code should be greater than 6ms and less than 40ms,
so reduce the delay before sending the initial code and avoid panel
exceptions.
