net/i40e/base: add AQ command for rearrange NVM structure

Browse Source 
During switching between old NVM structure approach (called
structured NVM) to new one (called flat NVM) or backward flash
needs to be rearranged to required NVM structure.
This is a part of transition from one NVM structure to another.
The function is introduced to command firmware to start
rearrangement process.
