acpi: fix ACPI generation for pci bridges
Commit 8dcf525abc5dff785251a881f9764dd961065c0d
acpi-build: append description for non-hotplug
appended description for all occupied non hotpluggable PCI slots.
However the bridge devices are already added to SSDT,
adding them again will create an incorrect SSDT table.
Fixed by skipping the pci bridge devices, marking them as 'system'.
