[PATCH 2/2] drm/rockchip: vop2: configure layers for vp3 on rk3588

[Heiko Stuebner <heiko@sntech.de>]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

The rk3588 VOP2 has 4 video-ports, yet the driver currently only
configures the first 3, as used on the rk3568.

Add another block to configure the vp3 as well, if applicable.

Fixes: 5a028e8f062f ("drm/rockchip: vop2: Add support for rk3588")
