ALSA: usb-audio: Deconflict VID between Focusrite Novation & MV-SILICON

MV-SILICON is a SoC manufacturer producing multifunctional audio SoCs.
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.
