Subject: [PATCH 1/2] drm/panel: sitronix-st7789v: add panel orientation support

Determine the orientation of the display based on the device tree and
propagate it.

While at it, fix the indentation in the struct drm_panel_funcs.

OK, if we agree that the indentation should be changed I'll be happy to
move the change to an extra patch.
