fixup! dts: bcm2712-rpi: Give PIO the "heavy" DMA channels

Use the simplified channel property declaration scheme, where the DMA
driver finds the best match based on positive matches with no hard
exclusions.

N.B. The new scheme should give the same results with old and new DTB,
with the old property name still be accepted for backwards-compatibility.
