 - Add annotations to dtx_diff output

 - Fix unittest reporting of expected error

 - Move DMA configuration for virtual devices into the driver that needs
   it (s5p-mfc)

 - Vendor prefixes for feiyang and techstar

 - Convert ARM GIC, GICv3, and L2x0 to DT schema

 - Add r8a7778/9 HSCIF serial bindings
