dt-bindings: firmware: Remove xlnx,zynqmp-firmware.txt file

The funtionality of xlnx,zynqmp-firmware.txt is replaced with
xlnx,zynqmp-firmware.yaml bindings so this patch removes the
zynqmp-firmware.txt file

-Device Tree Bindings for the Xilinx Zynq MPSoC Firmware Interface
------------------------------------------------------------------
-
-The zynqmp-firmware node describes the interface to platform firmware.
-ZynqMP has an interface to communicate with secure firmware. Firmware
-driver provides an interface to firmware APIs. Interface APIs can be
-used by any driver to communicate to PMUFW(Platform Management Unit).
-These requests include clock management, pin control, device control,
-power management service, FPGA service and other platform management
-services.
-
-Required properties:
- - compatible: Must contain any of below:
-               "xlnx,zynqmp-firmware" for Zynq Ultrascale+ MPSoC
-               "xlnx,versal-firmware" for Versal
- - method:     The method of calling the PM-API firmware layer.
-               Permitted values are:
-                 - "smc" : SMC #0, following the SMCCC
-                 - "hvc" : HVC #0, following the SMCCC
