drm/rockchip: vop: fix mask when updating interrupts
Commit dbb3d94 (drm/rockchip: vop: move interrupt registers into vop_data) introduced new macros for updating the interrupt control registers but these always use the mask from the register definition without refining it for the particular bits that are being changed. This means that whenever we enable/disable a particular interrupt we end up disabling all of the others as a side effect. Signed-off-by: John Keeping <john@metanate.com>
