bus: omap_l3_noc: introduce concept of submodule
While OMAP4 and OMAP5 had 3 separate clock domains, DRA7 has only 2 and the first one then is internally divided into 2 sub clock domains. To better represent this in the driver, we use the concept of submodule. The address defintions in the devicetree is as per the high level clock domain(module) base, the sub clockdomain/subdomain which shares the same register space of a clockdomain is marked in the SoC data as L3_BASE_IS_SUBMODULE. L3_BASE_IS_SUBMODULE is used as an indication that it's base address is the same as the parent module and offsets are considered from the same base address as they are usually intermingled. Other than the base address, the submodule is same as a module as it is functionally so.
