i2c: i801: Bring back Block Process Call support for certain platforms

Commit 9efa63335a1c ("i2c: i801: Use iTCO version 6 in Cannon Lake PCH
and beyond") looks like to drop by accident Block Write-Block Read Process
Call support for Intel Sunrisepoint, Lewisburg, Denverton and Kaby Lake.

That support was added for above and newer platforms by the commit
0a78aa40356c ("i2c: i801: Add Block Write-Block Read Process Call
support") so bring it back for above platforms.
