9a2654c0f6 drm/panel: Add and fill drm_panel type field
Add a type field to the drm_panel structure to report the panel type,
using DRM_MODE_CONNECTOR_* macros (the values that make sense are LVDS,
eDP, DSI and DPI). This will be used to initialise the corresponding
connector type.

Update all panel drivers accordingly. The panel-simple driver only
specifies the type for the known to be LVDS panels, while all other
panels are left as unknown and will be converted on a case-by-case
basis as they all need to be carefully reviewed.

6dbe0c4b0f drm/panel: Initialise panel dev and funcs through drm_panel_init()
Instead of requiring all drivers to set the dev and funcs fields of
drm_panel manually after calling drm_panel_init(), pass the data as
arguments to the function. This simplifies the panel drivers, and will
help future refactoring when adding new arguments to drm_panel_init().

The panel drivers have been updated with the following Coccinelle
semantic patch, with manual inspection to verify that no call to
drm_panel_init() with a single argument still exists.

expression panel;
expression device;
identifier ops;

-panel.dev = device;
-panel.funcs = &ops;

6cdd4e60f7 drm/panel: st7701: Swap vertical front and back porch timings
Vertical front and back porch values on existing driver are swapped.
The existing timings are still working as expected, but to make sure
it can compatible with techstar ts8550b bsp timings this patch swap

849b2e3ff9 drm/panel: Add Sitronix ST7701 panel driver
ST7701 designed for small and medium sizes of TFT LCD display, is
capable of supporting up to 480RGBX864 in resolution. It provides
several system interfaces like MIPI/RGB/SPI.

Currently added support for Techstar TS8550B which is ST7701 based
480x854, 2-lane MIPI DSI LCD panel.

Driver now registering mipi_dsi device, but indeed it can extendable
for RGB if any requirement trigger in future.
