ice: use less resources in switchdev

Michal Swiatkowski says:

Switchdev is using one queue per created port representor. This can
quickly lead to Rx queue shortage, as with subfunction support user
can create high number of PRs.

Save one MSI-X and 'number of PRs' * 1 queues.
Refactor switchdev slow-path to use less resources (even no additional
resources). Do this by removing control plane VSI and move its
functionality to PF VSI. Even with current solution PF is acting like
uplink and can't be used simultaneously for other use cases (adding
filters can break slow-path).

In short, do Tx via PF VSI and Rx packets using PF resources. Rx needs
additional code in interrupt handler to choose correct PR netdev.
Previous solution had to queue filters, it was way more elegant but
needed one queue per PRs. Beside that this refactor mostly simplifies
switchdev configuration.

* '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue:
  ice: count representor stats
  ice: do switchdev slow-path Rx using PF VSI
  ice: change repr::id values
  ice: remove switchdev control plane VSI
  ice: control default Tx rule in lag
  ice: default Tx rule instead of to queue
  ice: do Tx through PF netdev in slow-path
  ice: remove eswitch changing queues algorithm
