When using the Power big endian CPU for i40e NIC,
the current i40e related registers operations will cause a problem,
because the i40e registers are little endian which is inconsistent with
big endian CPU. Add the conversion for the inconsistency.

PATCH v2: Edit the comments make it more clear
PATCH v1: Add the endian conversion for registers operations.
