1b07caaea4 lib: simplefb: calculate font scaling factor dynamically
Instead of hardcoding it to 2 for all devices, scale it dynamically
per device width and height.

aa0163f2a5 lib: simplefb: drop passing fb base via func args
As we can make use of the video_info struct for base address,
this argument is not required anymore and only breaks havoc on
boards that don't set the CONFIG option.

579bbfa393 lib: break ABI by reworking simplefb and then fix it
Jokes aside, commit adds support for colored indexes based on the
loglevel, introduces a better simplefb probing that does not depend
on hardcoded config options. Implementing support for fdt should be
easier now.

3b517ba95a lib: debug: Introduce loglevels + many minor changes
Implement 8 loglevels to use with printk:

While at it, separate the font in a new "video" directory, which
also makes space for a proper video probing implementation. Fill
in the font from 32 to 256. Scale the font to render twice as big.
Implement dynamic line length detection. Change a few things here
and there to follow the linux kernel code style. Add a nice logo.
