serial: sh-sci: Kill off unused membase kludge.
All users of the platform port data specify a mapbase where the driver later derives the membase from. Now that UPF flags are taken in to account for generic ioremapping we can kill off the port-specific membase clobbering and simply use the generic paths. This derives from a time when sh64 was not capable of using the generic ioremap implementation and had employed early bolted DTLB mappings for port access, which is no longer an issue.
