[POWERPC] Fix console output getting dropped on platforms without udbg_putc

Previously, registering this early console would just result
in dropping early buffered printk output until a udbg_putc
was registered.

However, commit 69331af79cf29e26d1231152a172a1a10c2df511
clears the CON_PRINTBUFFER flag on the main console when a
CON_BOOT (early) console has been registered, resulting in
the buffered messages never being displayed to the user.

This fixes the problem by making sure we don't register udbg_console
on platforms that don't implement udbg_putc.
