Issue with RFDC device tree generator parameter names

[litghost]

Configuration

Vivado/PetaLinux/device-tree-xlnx at 2023.2 on Ubuntu 20.04

Expected behavior

Device tree writer correctly outputs NCOFreq parameters into device tree param-list.

Actual behavior

Device tree writer outputs NCOFreq as "0.0" to device tree param-list.

Issue

Between 2022.2 and 2023.2 the device tree writer for the RFDC driver added the NCOFreq parameter (see commit). However that commit reads from a parameter named C_DAC_NCO_FREQ00 (and C_DAC_NCO_FREQ01, etc). However Vivado appears to believe this parameter is named C_DAC_NCO_Freq00 (and C_DAC_NCO_Freq01, etc).

When the device tree generator is run on a design that contains an usp_rf_data_converter block, the device tree writer complains about not finding the relevant configuration:

WARNING: [Common 17-673] Cannot get value of property 'CONFIG.C_DAC_NCO_FREQ00' because this property is not valid in conjunction with other property setting on this object.

When checking the output device tree param-list, the output has all the NCO frequencies at 0.0 instead of the correct value.

As an experiment, I changed rfdc.tcl to use C_DAC_NCO_Freq00 instead of C_DAC_NCO_FREQ00, and this appears to resolve this issue. I suspect rfdc.tcl needs to updated to use the names used in Vivado?
