We shouldn't install them on the architectures Hyper-V doesn't support.
And, hv_ata_pci_disengage.4.gz should be removed from all architectures:
- It should have only applied to Hyper-V;
- For Hyper-V platforms (amd64 and i386), the related driver was removed by

because now we have a better mechanism to disble the ata driver for hard
disks when the VM runs on Hyper-V.
