Subject: [PATCH] ide: add "noacpi" / "acpigtf" / "acpionboot" parameters

* Rename ide_noacpi{tfs,onboot} to ide_acpi{gtf,onboot} (+ reverse logic).

* Move ide_*acpi* variables to ide-acpi.c and remove unnecessary initializers.

* Add "noacpi" / "acpigtf" / "acpionboot" parameters.

* Obsolete "ide=noacpi" / "ide=acpigtf" / "ide=acpionboot" kernel parameters.
