[PATCH 5/5] drm/rockchip: vop2: Use vop2->old_layer_sel directly in wait_for_layer_cfg_done()

[Cristian Ciocaltea]

After the old_layer_sel local was removed, the only caller of
rk3568_vop2_wait_for_layer_cfg_done() already passes vop2->old_layer_sel
as the expected value.

Drop the redundant parameter and read the member directly inside the
function.
