Refactor booting-without-of.txt

[Grant Likely]

Adding the Linux expected device tree bindings to
booting-without-of.txt seems to be getting a little unwieldy.  Plus
with more than one arch using the device tree (powerpc, sparc &
microblaze) the device tree bindings aren't necessarily powerpc only
(the Xilinx devices certainly fall in this category).

Anyone have comments about splitting the expected device tree bindings
out of booting-without-of.txt into a separate directory?

Perhaps something like this; each file contains common bindings for
the type of device and device specific properties:

Documentation/of/
Documentation/of/README - Description of the purpose and layout of
this directory
Documentation/of/net.txt - network device bindings (eth, MDIO, phy, etc)
Documentation/of/serial.txt - serial device bindings
Documentation/of/misc.txt - anything that doesn't fit anywhere else yet.
Documentation/of/soc/* - System on chip stuff that doesn't fit will
into established device types; possibly a separate file for each chip.
Documentation/of/usb.txt - usb blah blah blah
Documentation/of/whatever - you get the picture.

Thoughts?
