What I did
Add lpmode in sfputil.py for as7716-32xb.
.

Implement get_low_power_mode/set_low_power_mode in sfputil.py

Description for the changelog
Access eeprom from transceiver to get/set lpmode status
If "Power override" bit is not set, return the H/W pin status depended on H/W design.
For as7716-32xb, this pin is pulled low which is High Power Mode.
If "Power override" bit is set, retrun the S/W lpmode status read from eeprom.
Below is the Power Mode Truth Table defined in sff-8436
LPMode_Pin Power_overide_Bit Power_set_Bit Module_Power_Allowed
1 0 X Low Power
0 0 X High Power
X 1 1 Low Power
X 1 0 High Power
