serial: 8250: SERIAL_8250_EM should depend on ARCH_RENESAS

The Emma Mobile integrated serial port hardware is only present on Emma
Mobile SoCs.  Hence add a dependency on ARCH_RENESAS, to prevent asking
the user about this driver when configuring a kernel without Renesas
ARM32 SoC support.

          Selecting this option will add support for the integrated serial
          port hardware found on the Emma Mobile line of processors.
