The newly added internal rgb encoder for Rockchip vops is missing
stubs for the case that the rgb output part is not enabled in the
kernel config. So add these.

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;
