Subject: [PATCH] [PATCH] Fix and clean up quirk_intel_ide_combined()
 configuration

This change makes quirk_intel_ide_combined() dependent on the precise
conditions under which it is needed:

* IDE is built in
* IDE SATA option is not set
* ata_piix or ahci drivers are enabled

This fixes an issue where some modular configurations would not cause
the quirk to be enabled.
