i40e: Ioremap changes

Browse Source 
For future device support we do not want to map the whole CSR space since some
of it is mapped by other drivers with different mapping methods.

Note: As a side effect, the flash region (if exposed through the memory map)
gets unmapped too since it follows the future use region.
