MIPS: RB532: Avoid undefined early_serial_setup() without SERIAL_8250_CONSOLE
Currently MIPS allnoconfig with CONFIG_MIKROTIK_RB532=y fails to link due to missing support for early_serial_setup(): LD vmlinux arch/mips/rb532/serial.o: In function `setup_serial_port': serial.c:(.init.text+0x14): undefined reference to `early_serial_setup' Rather than adding dependencies to the platform to force inclusion of SERIAL_8250_CONSOLE together with it's dependencies like TTY, HAS_IOMEM, etc, just exclude arch/mips/rb532/serial.c from the build when it's dependency is not selected in the kernel config.
