[PATCH 05/52] drm/mipi_dbi: Use drmm_add_final_kfree in all drivers

[Daniel Vetter <daniel.vetter@xxxxxxxx>]

They all share mipi_dbi_release so we need to switch them all
together. With this we can drop the final kfree from the release
function.

Aside, I think we could perhaps have a tiny additional helper for
these mipi_dbi drivers, the first few lines around devm_drm_dev_init
are all the same (except for the drm_driver pointer).
