drm/panel: boe-tv101wum-nl6: restore MODE_LPM after sending disable cmds
When preparing the panel, it seems that it always expects commands to be
transferred in LP mode. However, the disable function removes the
MIPI_DSI_MODE_LPM flag, and no other function re-adds it.
As the unprepare function contains no DSI commands, re-adding the flag
just after disabling the panel should be safe. Add the code re-adding
the flag after the two commands for disabling the panel are sent.
This fixes error messages shown in kernel log when unblanking on
mt8183-kukui-kodama-sku32 device.
