Remove the VDEC_SYS register space from the decoder, so that the node address becomes that of VDEC_MISC, solving the long-standing conflicting addresses between this node and the vdecsys clock-controller node: arch/arm64/boot/dts/mediatek/mt8173.dtsi:1365.38-1369.5: Warning (unique_unit_address_if_enabled): /soc/clock-controller@16000000: duplicate unit-address (also used in node /soc/vcodec@16000000) The driver makes use of this register space, however, so also add a phandle to the VDEC_SYS syscon to maintain functionality.
