Already using devm_drm_dev_init, so very simple replacment.

drm/mipi-dbi: Drop explicit drm_mode_config_cleanup call
...
Allows us to drop the drm_driver.release callback from all
drivers, and remove the mipi_dbi_release() function.
This is made possible by a preceeding patch which added a drmm_
cleanup action to drm_mode_config_init(), hence all we need to do to
ensure that drm_mode_config_cleanup() is run on final drm_device
cleanup is check the new error code for _init().
v2: Explain why this cleanup is possible (Laurent).
v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas)

drm/mipi-dbi: Move drm_mode_config_init into mipi library
...
7/7 drivers agree that's the right choice, let's do this.
This avoids duplicating the same old error checking code over all 7
drivers, which is the motivation here.

drm/mipi_dbi: Use drmm_add_final_kfree in all drivers
...
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).

...
Add support for the Okaya RH128128T display to the st7735r driver on
DT-enabled systems.
The RH128128T is a 128x128 1.44" TFT display driven by a Sitronix
ST7715R TFT Controller/Driver. The latter is very similar to the
ST7735R, and can be handled by the existing st7735r driver.

drm: tiny: st7735r: Prepare for adding support for more displays
...
Currently the st7735r driver supports only a single display panel.
Prepare for adding support for other display panels by factoring out the
display-specific parameters in struct st7735r_cfg.
For now, the following parameters can be configured:
- Display resolution,
- Horizontal/vertical display offsets,
- Read-write versus read-only controllers,
- RGB versus BGR color component ordering.
Rename jd_t18003_t01_pipe_enable() and jd_t18003_t01_pipe_funcs() to
st7735r_pipe_enable() resp. st7735r_pipe_funcs(), as they are not really
specific to the Jianda JD-T18003-T01 display anymore.
