The binding was describing a single clock list for all platforms, but that's not really suitable: mt2712 requires an extra 'bus_clk' on some of its controllers, while mt8192 requires four different extra clocks. The rest of the platforms can share the same 3 clocks, with the third being optional as it's not present on all platforms. Move the clock definitions inside if blocks that match on the compatibles. In practice this gets rid of dtbs_check warnings on mt8192, since the 'bus_clk' clock from mt2712 is no longer expected on this platform.
