In struct pci_epc_features, an EPC driver can already specify if they
support MSI (by setting msi_capable) and MSI-X (by setting msix_capable).
Thus, for consistency, allow an EPC driver to specify if it supports
INTx interrupts as well (by setting intx_capable).
Since this struct is zero initialized, EPC drivers that want to claim
INTx support will need to set intx_capable to true.
