i40e: 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.
