Subject: [PATCH v1 1/1] drm/panel: boe-th101mb31ig002 : Fix the way to get porch parameters

The current driver can only obtain the porch parameters
of boe-th101mb31ig002. Modify it to obtain the porch
parameters of the panel currently being used.

Fixes: 24179ff9a2e4524 ("drm/panel: boe-th101mb31ig002 : Make it compatible with other panel.")

Signed-off-by: Zhaoxiong Lv <lvzhaoxiong@...qin.corp-partner.google.com>
