Use a general config_port interface instead. In addition, in mt2712, larb8 and larb9 are the bdpsys larbs which are not the normal larb, their register space are different from the normal one. thus, we can not call the general config_port. In mt8183, IPU0/1 and CCU connect with smi-common directly, they also are not the normal larb. Hence, we add a "larb_direct_to_common_mask" for these larbs which connect to smi-commmon directly. This is also a preparing patch for adding mt8183 SMI support.
