ARM: DRA7: hwmod: Add dra74x and dra72x specific ocp interface lists
commit f7f7a29bf0cf25af23f37e5b5bf1368b85705286 upstream. To deal with IPs which are specific to dra74x and dra72x, maintain seperate ocp interface lists, while keeping the common list for all common IPs. Move USB OTG SS4 to dra74x only list since its unavailable in dra72x and is giving an abort during boot. The dra72x only list is empty for now and a placeholder for future hwmod additions which are specific to dra72x.
