[coreboot] FILO bug disk not seen at ata-0 (Doesn't try to detect on ATA only SIL3114)

Hi Rudolf,

Awesome! This fixes booting from SATA on the s2881 for me with Seabios.

Before, even with the sii3114 option rom, Seabios never showed the disk as a
boot option in the boot menu.

Now I don't even need that sii3114 option rom anymore.

If you add a Signed-off-By line, this is

Thanks!
