drm/rockchip: Add support for Rockchip Soc RGB output interface
Some Rockchip CRTCs, like rv1108 and px30, can directly output parallel
and serial RGB data to panel or conversion chip.
So add a feature-bit for vops to mark the ability for these direct
outputs and add an internal encoder in that case, that can attach to
bridge chipsor panels.
Changes in v7:
1. forget to delete rockchip_rgb_driver and delete it.
Changes in v6:
1. Update according to Heiko Stuebner' implemention, rgb output is
part of vop's feature, should not register as a independent
driver.
Changes in v5:
1. add SPDX-License-Identifier tag
Changes in v4:
1. add support px30;
Changes in v3:
1. update for rgb-mode move to panel node.
Changes in v2:
1. add error log when probe failed;
2. update name_to_output_mode() according to sean's suggest;
3. Fix uninitialized use of ret.
