Add nodes for the SRAM available on atmel SoCs
For the at91sam9260 and the at91sam9g20, address mirroring is used to create a
single contiguous SRAM range instead of declaring two separate banks.

Also remove leftover TODOs in the sam9g45 file

During the submission of these new sama5d4 files, the GPL notice mentioned the
device tree as a library, which is not really accurate.
Fix all these library mentions to reflect the fact that it's actually just a
file.
