ARM: shmobile: r8a7791 SCIF support
Add SCIF serial port support to the r8a7791 SoC by adding platform devices for SCIFA0 -> SCIFA5 as well as SCIFB0 -> SCIFB2 and SCIF0 -> SCIF5 together with clock bindings. DT device description is excluded at this point since such bindings are still under development.
