Benoît Thébaudeau 04890b1899 cc2538: ccm: Allow separate input/output buffers
This is supported by the hardware, so give access to this feature in the
API.

Benoît Thébaudeau baef75752e cc2538: aes: Add support for generic operations
Add generic AES functions that should be able to support all the modes
of operation of the hardware AES crypto engine, i.e. ECB, CBC, CTR,
CBC-MAC, GCM, and CCM.

This makes it possible to easily implement these modes of operation
without duplicating code.

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.
