[PATCH v2 0/6] Resolve TYPE_PIIX3_XEN_DEVICE

[Bernhard Beschow <shentey@xxxxxxxxx>]

This series first renders TYPE_PIIX3_XEN_DEVICE redundant and finally removes
it. The motivation is to 1/ decouple PIIX from Xen and 2/ to make Xen in the PC
machine agnostic to the precise southbridge being used. 2/ will become
particularily interesting once PIIX4 becomes usable in the PC machine, avoiding
the "Frankenstein" use of PIIX4_ACPI in PIIX3.

v2:
- xen_piix3_set_irq() is already generic. Just rename it. (Chuck)

Testing done:
None, because I don't know how to conduct this properly :(

Based-on: <20221221170003.2929-1-shentey@xxxxxxxxx>
