Silicon/SynQuacer/AcpiTables: take presence detect of PCI0 into account
On the SynQuacer Evalution Board, PCIe RC #0 is not clocked if no card
is inserted into the PCIe slot, and so any attempt to access the device
registers will lock up the system.
So let's check the presence detect pin directly in the _STA implementation
of PCI0. This needs to be done before the config space check, because that
access itself will lock the system if no card is inserted.
