[BUG] Can't find export or definition for 'read_section_sv' and other used functions causing Fatal Errors when not found in any .so included with Questasim

[ahmedelalfy94]

Is there an existing CVA6 bug for this?

• I have searched the existing bug issues

Bug Description

There is some DPI functions that are not declared in either
libfesvr disasm libcustomext libfdt libriscv libsoftfloat or uvm_dpi.so related to questa
for the below functions:

• 'debug_tick'
• 'get_section'
• 'jtag_tick'
• 'read_elf'
• 'read_section_sv'
• 'read_symbol'

While running test questa-testharness_sim/rv64ui-v-addiw.cv64a6_imafdc_sv39 the following FATAL error happened
Fatal: (vsim-160) /workspace/cva6/corev_apu/tb/ariane_tb.sv(28): Null foreign function pointer encountered when calling 'read_elf'

I think if they are not essentially needed you can reduce the fatal message into suppressible one.

Update: I found read_elf, but still can't find 'read_symbol' or 'read_section_sv' Need there definitions.
