Many budget-oriented OEM devices are built on top of them. However, some of them are just too budget-constrained that their manufacturers didn't even have a USB VID and simply picked a random VID. Some OEMs unfortunately picked the VID of Focusrite Novation (0x1235), resulting in VID conflicts as we had defined a VENDOR_FLG() for the latter. Add a VENDOR_STRING_FLG() for MV-SILICON to stop the matching procedure for these quirky devices, so that quirk flags for Focusrite Novation won't be accidentally applied on them.
