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

Add a DT node for the TRNG (True Random Number Generator) block.

Keep this block enabled as it does not depend on any external connection,
and thus should be available on all boards.

The G45 and 9263 SoCs has two identical ram controller, that are defined as a
single node, with two reg cells.

The proper way to support such a case is to have two separate DT nodes.
