[PATCH v2 0/3] media: pci: mgb4: Add support for GMSL1 and GMSL-coax modules

From: Martin Tůma <martin.tuma@xxxxxxxxxxxxxxxxxxxxx>

This patches add support for two new mgb4 card modules - GMSL1 and
GMSL3-coax. The GMSL3-coax module is a variant of the already supported
GMSL3 module with a coaxial interface instead of a twisted-pair interface.
The GMSL1 module is completely new and requires a separate FW type as well.

Changes from v1 to v2:
* Properly use NULL instead of 0.
* Fixed missing "media" prefix in patch #2.
