[PATCH] serial: fix Kconfig for Freescale 16550

[Michael Neuling]

next-20111212 breaks with linking a pmac32_defconfig with:
  drivers/built-in.o: In function `fsl8250_handle_irq':
  (.text+0x7ba74): undefined reference to `serial8250_modem_status'
  drivers/built-in.o: In function `fsl8250_handle_irq':
  (.text+0x7baa4): undefined reference to `serial8250_tx_chars'
  drivers/built-in.o: In function `fsl8250_handle_irq':
  (.text+0x7bab4): undefined reference to `serial8250_rx_chars'

Caused by:
  9deaa53 serial: add irq handler for Freescale 16550 errata.

pmac32_defconfig results in SERIAL_8250_FSL=y but SERIAL_8250=m so
8250_fsl.c doesn't link properly.  

This explicitly makes SERIAL_8250_FSL depends on SERIAL_8250=y.

I'm not sure this is the right fix as it seems like a Kconfig bug.
