acpi: build PCI hotplug devices from a single template
More than 1kb of data is taken by the 32 copies of the PCI hotplug SSDT
methods. We can build them from a single template like we do for CPUs
(wrapped in a Scope(\_SB.PCI0) block).
Three items differ for each slot: the device name, bits 16-23 of _ADR,
the _SUN value. On top of this we have to rename the eject method for
non-removable slots, like we already do in build_pcihp.
There is a small change in the ASL: instead of including the number of
the slot in the implementation of _EJ0, we just call _SUN. This is also
similar to what we do for CPU hotplug.
Once we do this, there is no need to keep a separate SSDT for PCI hotplug.
Everything can reside in the same table.
