Google/Snow: Remove unnecessary serial console init code.

The "console_init" does initialize UART driver (which will setup peripheral and
pinmux) and print starting message. Duplicated initialization can be removed.

Also, console_init (from console.c) is always linked to bootblock (and will do
nothing if CONFIG_EARLY_CONSOLE is not defined) so it's safe to remove #ifdef.

Verified by building and booting on Google/Snow, with and without
CONFIG_EARLY_CONSOLE.
