[ Upstream commit fc1ccc16271a0526518f19f460fed63d575a8a42 ]
For the "starry, 2081101qfh032011-53g" panel, it is stipulated in the
panel spec that MIPI needs to keep the LP11 state before the
lcm_reset pin is pulled high.
Fixes: 6069b66cd962 ("drm/panel: support for STARRY 2081101QFH032011-53G MIPI-DSI panel")
