Use physmap_of to access RAMs as mtd and add documenation for it. This approach
is a lot less intrusive as adding an of-wrapper around plat-ram.c. As most
extensions of plat-ram.c (e.g. custom map-functions) can't be mapped to the
device tree anyhow, extending physmap_of seems to be the cleanest approach.
Tested with a phyCORE-MPC5121e.

Add binding for mtd nodes with multiple reg tuples. Multiple reg tuples
are used when the flash region covers multiple devices of the same type,
but not necessarily the same size.

It's easier to find bindings descriptions in separate files. So factor
out the MTD physmap bindings into a separate file to not clutter
booting-without-of.txt more.
