Benoît Thébaudeau 801315e819 cc2538: aes: Make it possible to have several keys stored at once
Several keys can be kept at the same time in the key store, and several
keys can be loaded at once. Give access to these features.

The ccm-test example is also improved to better demonstrate the use of
the key store.

Benoît Thébaudeau b92a5afcc4 cc2538: ccm: Make it possible to use the interrupt
Using the AES interrupt allows the user process not to waste time
polling for the completion of the operation. This time can be used by
the user process to do something else, or to let the system enter PM0.

Since the system is now free to perform various operations during a
crypto operation, a protection of the crypto resource is added, and PM1+
is prohibited in order not to stall crypto operations.
