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.

Since we're practically PIC, keep the massive array in the header.
Otherwise we exception.

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.
