Store mac to eeprom enhancement

1. Add delay after write mac to eeprom before read back to verify.
Issue: Some eeprom has timing requirement to allow internal write cycle
to complete.

2. Make sure MAC address are written within one EEPROM page.
Issue: Block write rolls over back to start of same page. Use 8bytes as
page size. It works also on 16byte page device.

3. Add mac header and checksum for mac record.

Tested:
Write MAC and Read MAC commands complete successfully
