net/i40e/base: add function to read LPI statistics

Browse Source 
There was no time duration statistics for LPI (Low Power Idle)
in EEE (Energy-Efficient Ethernet).
Added new procedure to get duration values from FW.
Otherwise there is no available procedure to get tx_lpi_duration
and rx_lpi_duration values.
