i40e: Clean up handling of private flags
This patch cleans up and addresses several issues in the way that i40e
handles private flags. Previously the code was choosing fixed bits and
trying to match them up with strings in a somewhat haphazard way. This
resulted in the possibility for adding a new bit and causing a mismatch as
the private flags are linear bits starting at 0, and the private flags in
the driver were split up over a group specific to the PF and a group that
was global.
What this change does is define an array of structs used to represent the
private flags. Contained within the structs are the bits necessary to know
which flags to set and/or clear depending on the state of the bit. By
doing this we can add new bits in the future with minimal overhead and
avoid creating possible mis-matches should we need to remove a flag based
on compile options.
