crypto: atmel-i2c - Fix build error while CRC16 set to m 

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
