[PATCH v1 0/2] drm: rcar-du: Repair vblank event handling

[Kieran Bingham]

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
