[ Upstream commit 9a2654c0f62a1704f36acb6329f9ccbd539f75ad ]
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.

[ Upstream commit 6dbe0c4b0fc0646442b2b1580d022404e582fd7b ]
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.

Currently, ret is being checked for an error condition however it
is not being assigned in the previous statement on the call of
function mipi_dsi_dcs_exit_sleep_mode. Add in the missing assignment
of ret.

The LHR050H41 panel is the panel shipped with the BananaPi M2-Magic, and is
based on the Ilitek ILI9881c Controller. Add a driver for it, modelled
after the other Ilitek controller drivers.
