QL-MemoryBank-Flatten "num_wl" is ignored when "num_regions" is defined

[mustafaarslan0]

Describe the bug
"num_wl" of "ql_memory_bank_config_setting" is ignored when "num_regions" of "configuration_protocol" is defined (even if num_regions=1). It works if "num_regions" is not defined.

  <configuration_protocol>
    <organization type="ql_memory_bank" circuit_model_name="SRAM" num_regions="4">
      <bl protocol="flatten"/>
      <wl protocol="flatten"/>
    </organization>
    <ql_memory_bank_config_setting>
      <pb_type name="clb" num_wl="32"/>
    </ql_memory_bank_config_setting>

To Reproduce

1. Clone latest main OpenFPGA repository
2. Define "num_regions" in OpenFPGA arch file: k4_N4_40nm_qlbankflatten_defined_wl_openfpga.xml
3. Execute OpenFPGA task: ql_memory_bank_flatten_defined_wl
4. See that "num_wl" is ignored and OpenFPGA try to equalize number of BL and WLs.
