[PATCH 4/7] PCI: endpoint: Add intx_capable to epc_features

[Niklas Cassel <cassel@kernel.org>]

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.
