nicintel_eeprom: refactor i210 variable into reentrant pattern

Browse Source 
Move global Intel I210 specific variable into a struct and store
within the opaque_master data filed for the life-time of the driver.

This is one of the steps on the way to move opaque_master data
memory management behind the initialisation API.
