serial-uartlite: add earlycon support
Microblaze currently uses the old earlyprintk system, rather than the unified earlycon support, to show boot messages on uartlite. Add earlycon support so that other archs using uartlite can benefit from it. The new code in uartlite.c is copied almost verbatim from arch/microblaze/kernel/early_printk.c.
