The recent changes to the rcar-du driver to fix a race condition inadvertently change the order of which vblanks are reported.
Correct this by handling vblank events in the same completion handler. This removes the need for the IRQ handler on DU instances which are sourced by a VSP1.
For other platforms (Gen2) the vblank handler was enabling the VBK interrupt, but parsing on the FRM interrupt. Fix this by enabling the FRM interrupt using the FRE bit in the DIER register
