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.

-Metronomefb is a driver for the Metronome display controller. The controller
-is from E-Ink Corporation. It is intended to be used to drive the E-Ink
-Vizplex display media. E-Ink hosts some details of this controller and the
-display media here http://www.e-ink.com/products/matrix/metronome.html .
-
-Metronome is interfaced to the host CPU through the AMLCD interface. The
-host CPU generates the control information and the image in a framebuffer
-which is then delivered to the AMLCD interface by a host specific method.
-The display and error status are each pulled through individual GPIOs.
-
-Metronomefb is platform independent and depends on a board specific driver
-to do all physical IO work. Currently, an example is implemented for the
-PXA board used in the AM-200 EPD devkit. This example is am200epd.c
-
-Metronomefb requires waveform information which is delivered via the AMLCD
-interface to the metronome controller. The waveform information is expected to
-be delivered from userspace via the firmware class interface. The waveform file
-can be compressed as long as your udev or hotplug script is aware of the need
-to uncompress it before delivering it. metronomefb will ask for metronome.wbf
-which would typically go into /lib/firmware/metronome.wbf depending on your
-udev/hotplug setup. I have only tested with a single waveform file which was
-originally labeled 23P01201_60_WT0107_MTC. I do not know what it stands for.
-Caution should be exercised when manipulating the waveform as there may be
-a possibility that it could have some permanent effects on the display media.
-I neither have access to nor know exactly what the waveform does in terms of
-the physical media.
-
-Metronomefb uses the deferred IO interface so that it can provide a memory
-mappable frame buffer. It has been tested with tinyx (Xfbdev). It is known
-to work at this time with xeyes, xclock, xloadimage, xpdf.
