Max Makarov 87ba83bb01 vmm: pci_segment: use segment id as ACPI _UID ...

The ACPI specification requires _UID to be unique across devices
sharing the same _HID (ACPI 6.5 section 6.1.12). Currently every
PciSegment emits _UID=0 for its PNP0A08 host bridge, which violates
the spec when num_pci_segments > 1.

Windows guests detect this during ACPI namespace enumeration and
abort boot with BSOD 0xA5 ACPI_BIOS_ERROR, pointing at the _UID
object of the second PNP0A08 node. Linux guests are lenient and
silently accept the collision, so the issue has gone unnoticed.

Use self.id as _UID, matching what _SEG does on the line above.
For single-segment VMs (id == 0) this is a no-op at runtime.
