[PATCH 2/3] drm/rockchip: vop2: Skip UV plane setup for packed YUV formats

[Chaoyi Chen <kernel@airkyi.com>]

From: Chaoyi Chen <chaoyi.chen@rock-chips.com>

Packed YUV formats store chroma interleaved with luma in the same plane,
so they have no plane 1 that the UV address registers could point at.

Restrict both the plane 1 offset calculation and the UV register writes
to formats with more than one plane.
