[PATCH v2 2/2] serial: 8250: SERIAL_8250_FSL should depend on Freescale platforms

The Freescale 16550-style UART is only present on some Freescale SoCs.
Hence tighten the dependencies to prevent asking the user about this
driver, and possibly defaulting it to be enabled, when configuring a
kernel without appropriate Freescale SoC or ACPI support.
