[PATCH v2 2/2] staging: axis-fifo: remove superseded text binding

[Daniel28972897]

This driver's devicetree binding has been converted to
Documentation/devicetree/bindings/misc/xlnx,axi-fifo-mm-s.yaml,
which supersedes and duplicates this file.

-Xilinx AXI-Stream FIFO v4.1 IP core
-
-This IP core has read and write AXI-Stream FIFOs, the contents of which can
-be accessed from the AXI4 memory-mapped interface. This is useful for
-transferring data from a processor into the FPGA fabric. The driver creates
-a character device that can be read/written to with standard
-open/read/write/close.
-
-See Xilinx PG080 document for IP details.
-
-Currently supports only store-forward mode with a 32-bit
-AXI4-Lite interface. DOES NOT support:
-	- cut-through mode
-	- AXI4 (non-lite)
-
-Required properties:
-- compatible: Should be one of:
-    "xlnx,axi-fifo-mm-s-4.1"
-    "xlnx,axi-fifo-mm-s-4.2"
-    "xlnx,axi-fifo-mm-s-4.3"
-- interrupt-names: Should be "interrupt"
-- interrupt-parent: Should be <&intc>
-- interrupts: Should contain interrupts lines.
-- reg: Should contain registers location and length.
-- xlnx,axi-str-rxd-protocol: Should be "XIL_AXI_STREAM_ETH_DATA"
