[PATCH] mtd: make sure address-cells/size-cells are set when adding partition nodes

[Michael Olbrich]

address-cells/size-cells can either be set to 1 or 2 for 32 or 63 bit
addresses respectively. Barebox currently writes 32 bit addresses.
This makes sure that address-cells/size-cells are both set and have the
correct value.

Hi,

this is just a minor fix. What is really needed it support for 64 bit
addressing. Also, the bindings documentation says that all partitions
should be in a 'partitions' sub node. The main question here is probably
which kernel version introduced these features and what should be supported
by barebox.
