cc2538: Define and use device features
Define the available CC2538 devices and their features, and use them to define the linker script memory regions. The .nrdata output section is now always defined in order to trigger an error if it is used but no memory is available for it. The CC2538 device used by Contiki is made a configuration option, the CC2538SF53 device being the default. This makes more sense than defining the flash memory address and size as configuration options like previously, all the more not all values are possible and all the features are linked by each device. This change also makes it possible to: - use the correct SRAM parameters for the CC2538NF11, - know at build time if the AES, SHA, ECC and RSA hardware features are available on the selected CC2538 device.
