drm/rockchip: Load crtc devices in preferred order

On RK3399 the VOPL is loaded before VOPB and get registered as crtc-0.
However, on RK3288 and PX30 VOPB is gets registered as crtc-0 instead of
VOPL.

With VOPL registered as crtc-0 the kernel kms client is not able to
enable 4K display modes for console use on RK3399.

Load VOPB before VOPL to help kernel kms client make use of 4K display
modes for console use on RK3399.
