3d3d6df856 refactor: move x86_64 ACPI to board/x86_64 
Module ACPI should only include helpers for individual tables.
Putting tables together is architecture dependent.

3160823378 feat(pci)!: reserve a BDF before adding a device 
MSI on aarch64 requires an additional devid, which is usually the
device BDF. Thus the `MsiSender` of a PCI device needs to know the
BDF. However, currently the BDF is unknown until the device
has been plugged into the PCI bus.

This commit changes the API such that a BDF is reserved first before
a device is plugged in. The reserved BDF then can be passed to the
constructor of an `MsiSender`.
