drm: zte: add initial vou drm driver It adds the initial ZTE VOU display controller DRM driver. There are still some features to be added, like overlay plane, scaling, and more output devices support. But it's already useful with dual CRTCs and HDMI monitor working.

drm: zte: make zx_plane accessible from zx_vou driver Move struct zx_plane from zx_plane.c to zx_plane.h, so that it can be accessed from zx_vou driver, and we can save the use of struct zx_layer_data completely. More importantly, those additional data used by VOU controller to enable/disable graphic and video layers can later be added and accessed much more easily from zx_vou driver. While at it, we make two changes to zx_plane_init() interface: - Encode struct device pointer in zx_plane, so that we do not need to pass it as a parameter. - Change return of zx_plane_init() from struct drm_plane pointer to error code, since we can get the pointer from zx_plane in zx_vou driver now.
