net: dsa: qca8k: add additional MIB counter and make it dynamic
We are currently missing 2 additionals MIB counter present in QCA833x
switch.
QC832x switch have 39 MIB counter and QCA833X have 41 MIB counter.
Add the additional MIB counter and rework the MIB function to print the
correct supported counter from the match_data struct.
