[Intel-wired-lan] [next PATCH S62 3/6] i40e: use register for XL722 control register read/write

[Bimmy Pujari]

From: Paul M Stillwell Jr <paul.m.stillwell.jr at intel.com>

The XL722 doesn't support the AQ command to read/write the control
register so enable it to bypass the check and use the direct read/write
method.
