crypto: atmel-i2c - add support for SHA204A random number generator
The Linaro/96boards Secure96 mezzanine contains (among other things) an Atmel SHA204A symmetric crypto processor. This chip implements a number of different functionalities, but one that is highly useful for many different 96boards platforms is the random number generator. So let's implement a driver for the SHA204A, and for the time being, implement support for the random number generator only.
