media: dt-bindings: mediatek,vcodec: Remove VDEC_SYS register space

The binding expects the first register space to be VDEC_SYS. 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.

Also add reg-names to be able to tell that this new register schema is
used, so the driver can keep backward compatibility.

dt-bindings: media: mediatek,vcodec: Remove dma-ranges property

After commit f1ad5338a4d5 ("of: Fix "dma-ranges" handling for bus
controllers"), the dma-ranges of the leaf node doesn't work. Remove
it for vcodec here.

For mediatek,vcodec-decoder.yaml and mediatek,vcodec-encoder.yaml,
this property is in the leaf node, it is invalid as the above comment.

Currently there is only mt8195 VENC node has this property in upstream.
Indeed, VENC is affected, but it is not a fatal issue. Originally it
expects its iova range locate at 4GB-8GB. However after that commit, its
expectation doesn't come true, it will fall back to 0-4GB iova and also
could work well.

After adding device_link between the consumer with the smi-larbs,
if the consumer call its owner pm_runtime_get(_sync), the
pm_runtime_get(_sync) of smi-larb and smi-common will be called
automatically. Thus, the consumer don't need this property.

And IOMMU also know which larb this consumer connects with from
iommu id in the "iommus=" property.
