x86, boot: Don't compile early_serial_console.c when !CONFIG_EARLY_PRINTK
All the code in early_serial_console.c gets compiled out if !CONFIG_EARLY_PRINTK, but early_serial_console.o itself still gets compiled in. Eliminate it from the compile entirely in that case. This does not change the generated code at all, in either case. Signed-off-by: Josh Triplett <josh@joshtriplett.org>
