Mauro Carvalho Chehab ab42b81895 docs: fb: convert docs to ReST and rename to *.rst
The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Also, removed the Maintained by, as requested by Geert.

efifb is only for EFI booted Intel Macs.
Supported Hardware
==================
- iMac 17"/20"
- Macbook
- Macbook Pro 15"/17"

How to use it?

video=efifb:macbook
MacMini :
video=efifb:mini
Macbook Pro 15", iMac 17" :
video=efifb:i17
Macbook Pro 17", iMac 20" :
video=efifb:i20
Accepted options:
======= ===========================================================
nowc Don't map the framebuffer write combined. This can be used
to workaround side-effects and slowdowns on other CPU cores
when large amounts of console data are written.
