[centec] fix some bugs on centec tsingma bsp and v682 sonic_platform package (#10685)

#### Why I did it
Fix some bugs on centec tsingma bsp and v682 sonic_platform package.

#### How I did it
1.  add module license for centec mars phy driver
2.  Fix i2c function ability setting for tsingma soc i2c controller
3.  Fix eeprom read error on v682 sonic_platform sfp module

#### How to verify it
Build SONiC image and verify it on centec E530-48T4X and V682-48Y8C board.
