dt-bindings: dma: xlnx,axi-dma: Restore xlnx,flush-fsync as u32
The DT schema conversion incorrectly changed xlnx,flush-fsync from a u32
property to a boolean. The original binding documented values 1, 2, and 3
to select which VDMA channel(s) flush on frame sync.
Restore the uint32 type with the documented enum values and fix the
example accordingly.
