drm/rockchip: vop2: remove the plane number check in vop2_plane_mask_check()

Browse Source 
The &vop2_data.nr_layers represents the max number of planes that can
be assigned to one VP. Therefore, when checking the max plane number for
VOP2, it may be incorrect to use the &vop2_data.nr_layers.

And the comparison of assigned plane_mask with &vop2_data.plane_mask_base
can already confirm whether every plane has been assigned to one of all
the VPs.
