PCI: pci-bridge-emul: Set PCI_STATUS_CAP_LIST for PCIe device

commit 3be9d243b21724d49b65043d4520d688b6040b36 upstream.

Since all PCI Express device Functions are required to implement the PCI
Express Capability structure, Capabilities List bit in PCI Status Register
must be hardwired to 1b. Capabilities Pointer register (which is already
set by pci-bride-emul.c driver) is valid only when Capabilities List is set
to 1b.
