serial: sh-sci: Move private definitions to private header file
Move private register definitions and enums from the public <linux/serial_sci.h> header file to the driver private "sh-sci.h" header file. The common Serial Control Register definitions are left in the public header file, as they're needed to fill in plat_sci_port.scscr on legacy systems not using DT.
