HW set qsfp port to reset at default. so need SW to set to normal when boot.
1. Modify cpld driver to invert reset offset value
2. Set to normal when boot.
**- Why I did it**
The tx_disable function isn't work for the accton_ax5835-54x device.
**- How I did it**
Fix the incorrect path of the sfp node path inside the util file.
**- How to verify it**
Test with
"sudo accton_as5835_54x_util.py show"
"sudo accton_as5835_54x_util.py set sfp"
There should see correct value for module_present and module_tx_disable. And should able to set it.
