media: pci: Fill v4l2_fmtdesc with designated initializers
Replace initialization of static const v4l2_fmtdesc instances that specify every struct member with designated initializers. This allows not zeroing the reserved fields explicitly, and will avoid a need to patch these drivers every time a reserved field is repurposed.
