PCI: aardvark: Set PIO_ADDR_LS correctly in advk_pcie_rd_conf()

Browse source

commit 4fa3999ee6 upstream.

When setting the PIO_ADDR_LS register during a configuration read, we
were properly passing the device number, function number and register
number, but not the bus number, causing issues when reading the
configuration of PCIe devices.
