crypto: atmel-ecc - introduce Microchip / Atmel ECC driver
Add ECDH support for ATECC508A (I2C) device. The device features hardware acceleration for the NIST standard P256 prime curve and supports the complete key life cycle from private key generation to ECDH key agreement. Random private key generation is supported internally within the device to ensure that the private key can never be known outside of the device. If the user wants to use its own private keys, the driver will fallback to the ecdh software implementation.
