[PATCH] dmaengine: xilinx: Treat "xlnx,flush-fsync" as a flag

["Rob Herring (Arm)" <robh@kernel.org>]

The Xilinx DMA binding documents "xlnx,flush-fsync" as a boolean flag.
The driver read it as an integer cell and warned when it was absent,
which does not match the documented property encoding.

Use the boolean helper so the driver follows the binding. Leave
"xlnx,irq-delay" as an 8-bit property read because the hardware field
is 8 bits wide.
