drm/rockchip: Fix an error handling path rockchip_dp_probe()

[ Upstream commit 5074376822fe99fa4ce344b851c5016d00c0444f ]

Should component_add() fail, we should call analogix_dp_remove() in the
error handling path, as already done in the remove function.

Fixes: 152cce0006ab ("drm/bridge: analogix_dp: Split bind() into probe() and real bind()")
