The datasheet only lists one dummy byte in the 0xEB operation for the
following chips:
* GD5F1GQ4xExxG
* GD5F1GQ4xFxxG
* GD5F1GQ4UAYIG
* GD5F4GQ4UAYIG

Reto Schneider:
- Linux patch ported to U-Boot
- Checked for compatibility with GD5F1GQ4xBxxG
- Fixed operation code in original commit message (0xEH -> 0xEB)
