If CRYPTO_DEV_ATMEL_ECC is set m, which select CRC16 to m,
while CRYPTO_DEV_ATMEL_SHA204A is set to y, building fails.
drivers/crypto/atmel-i2c.o: In function `atmel_i2c_checksum':
atmel-i2c.c:(.text+0x16): undefined reference to `crc16'
Add CRC16 dependency to CRYPTO_DEV_ATMEL_SHA204A, and also make
CRYPTO_DEV_ATMEL_ECC depends on CRC16.
