nfc: s3fwrn5: Add missing CRYPTO_HASH dependency

The driver uses crypto hash functions so it needs to select CRYPTO_HASH.
This fixes build errors:

  arc-linux-ld: drivers/nfc/s3fwrn5/firmware.o: in function `s3fwrn5_fw_download':
  firmware.c:(.text+0x152): undefined reference to `crypto_alloc_shash'
