Stop using early_putc immediately after configuring console with cninit()
Early UART should be released right after system console initialization is completed. Otherwise, after cninit() both early and system console coexist what may lead to various issues (i.a. writing to unmapped early UART address). This cannot be done in cninit_finish() since it can be called late at the end of MI configuration. Obtained from: Semihalf Reviewed by: andrew Sponsored by: The FreeBSD Foundation
