devices: vfio_pci: identify intel-lpss devices via cmdline

intel-lpss devices need special handling during BAR accesses due to PV
operations in the guest (when compiled with the direct feature). Allow
identification of such devices via a new vfio parameter, intel-lpss, so
that it can tag them for PV handling.

BUG=b:232887201
TEST=crosvm accepts the intel-lpss parameter in --vfio

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
