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.
