Commit b1442c55ce8977aa ("serial: 8250: extend compile-test coverage")
added compile-test support to the Freescale 16550 driver. However, as
SERIAL_8250_FSL is an invisible symbol, merely enabling COMPILE_TEST now
enables this driver.
Fix this by making SERIAL_8250_FSL visible. Tighten the dependencies to
prevent asking the user about this driver when configuring a kernel
without appropriate Freescale SoC or ACPI support.

Yes, it's ugly, but I see no better solution. Do you?
