Jiri Slaby 6c614044ff V4L/DVB: media: dvb/af9015, implement eeprom hashing
This will be useful for matching of IR tables later.

We read the eeprom anyway for dumping. Switch the dumping to
print_hex_dump_bytes and compute hash above that by
hash = 0;
for (u32 VAL) in (eeprom):
  hash *= GOLDEN_RATIO_PRIME_32
  hash += VAL; // while preserving endinaness

The computation is moved earlier to the flow, namely from
af9015_af9013_frontend_attach to af9015_read_config, so that
we can access the sum in af9015_read_config already.
