However this register space is already assigned to a different node on both MT8173 and MT8183: a clock-controller node called 'vdecsys' which is also a syscon. In order to resolve the overlapping address ranges, remove the VDEC_SYS register space from the video decoder, and add a new property to hold the phandle to the syscon, so that iospace can still be handled.

To achieve that, rely on a vdecsys syscon to be passed through the DT, and use it to directly read the VDEC_HW_ACTIVE bit during IRQ handling to check whether the HW is active. Also update the VP8 stateful decoder to use the syscon, if present, for writes to VDEC_SYS. The old behavior is still present when reg-names aren't supplied, as to keep backward compatibility.
