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-testing
now enables this driver.

Fix this by dropping the COMPILE_TEST default again, but making the
SERIAL_8250_FSL symbol visible instead.
