Subject: [PATCH] drm/panel: osd-osd101t2587-53ts: migrate to
 mipi_dsi_turn_on_peripheral_multi

Documentation/gpu/todo.rst lists to transition away from using
deprecated methods in drm_mipi_dsi.c, so migrating from
mipi_dsi_turn_on_peripheral to mipi_dsi_turn_on_peripheral_multi.

Used commit e139c0eb22ce ("drm/panel: mantix-mlaf057we51: transition
to mipi_dsi wrapped functions") as a reference.

Signed-off-by: Matt Smith <matthew.j.smith2@...look.com>
