[0/3] PIIX3-IDE XEN cleanup

Message

This patch series first removes the redundant "piix3-ide-xen" device class and
then moves a XEN-specific helper function from PIIX3 code to XEN code. The idea
is to decouple PIIX3-IDE and XEN and to compile XEN-specific bits only if XEN
support is enabled.

Testing done:
'qemu-system-x86_64 -M pc -m 1G -cdrom archlinux-2022.05.01-x86_64.iso" boots
successfully and a 'poweroff' inside the VM also shuts it down correctly.

XEN mode wasn't tested for the time being since its setup procedure seems quite
sophisticated. Please let me know in case this is an obstacle.
