msm: msm_bus: Change initcall to subsys for bus devices

This change is required to enable early initialization of fabric
devices using device tree.
In the absence of this change, or if module_init/arch_init
are used, client registration is attempted before the
NoCs or fabrics are initialized. The registration fails
as the path cannot be calculated as the topology is built
after all the NoCs/Fabrics are initialized.
