Subject: [PATCH v2 4/5] bus: mhi: host: pci_generic: Add SRIOV support for
 PCIe device

From: Vivek Pernamitta <quic_vpernami@...cinc.com>

Add SR-IOV support for PCIe devices.
pci_sriov_configure_simple() will enable or disable SR-IOV for devices
that don't require any specific PF setup before enabling SR-IOV.
