It's fine to add vendor ids detect code, but I think config
'IDE_TO_AHCI' should be reserved.
Because there are three ways to control AHCI controller.

1. AHCI option rom.
2. ATA emulation mode in ATA.c.
3. non-ATA emulation mode in AHCI.c.

Config 'AHCI' can control non-ATA emulation mode enable/disable in
AHCI.c and we also need config 'IDE_TO_AHCI' to control ATA emulation
mode enable/disable in ATA.c.
