[PATCH] video: console: Fix default font selection

[Ondřej Jirman]

From: Ondrej Jirman <megi at xff.cz>

Some callers expect to call this with NULL font name to select the
default font (eg. boot/scene.c). Without handling the NULL condition
U-Boot crashes instead of displaying a bootflow GUI menu.
