sh: sh4a scif pdata (sh7757/sh7763/sh7770/sh7780/sh7785/sh7786/x3)
This patch breaks out the sh4a scif serial port platform data from a shared platform device to one platform device per port. Also, add serial ports to the list of early platform devices. All sh4a except SuperH Mobile processors are modified by this patch. While at it, sh7757 gets early platform device support.
