[PATCH v2 04/14] drm/bridge: ti-sn65dsi86: Reorder remove()

Let's make the remove() function strictly the reverse of the probe()
function so it's easier to reason about.

NOTES:
- The MIPI calls probably belong in detach() but will be moved in a
separate patch.
- The cached EDID freeing isn't actually part of probe but needs to be
in remove to avoid orphaning memory until better handling of the
EDID happens.

This patch was created by code inspection and should move us closer to
a proper remove.
