The aggregator list needs to be preserved for use after a reset. This
patch moves it out of the port_info instance and into the ice_hw instance.

This patch includes below changes to resolve the issue of ETS bandwidth
shaping to work.
1. Allocation of Tx queues is accounted for based on the enabled TC's
in ice_vsi_setup_q_map() and enabled the Tx queues on those TC's via
ice_vsi_cfg_txqs()
2. Get the mapped netdev TC # for the user priority and set the priority
to TC mapping for the VSI.

Before releasing the VSI, remove the VSI scheduler node. If not,
the node is left in the scheduler tree and, on subsequent load, the
scheduler tree contains the node so it does not set it in vsi_ctx.
This, later, causes the node to not be found in ice_sched_get_free_qparent
which leads to a "Failed to set LAN Tx queue context, error: -1".
To remove the scheduler node, this patch introduces ice_rm_vsi_lan_cfg
and related helpers.

This patch is a continuation of the previous patch where VSI
handles are used instead of VSI numbers.

This patch adds the ability for a VSI to use multiple Tx queues. More
specifically, the patch
1) Provides the ability to update the Tx scheduler tree in the
firmware. The driver can configure the Tx scheduler tree by
adding/removing multiple Tx queues per TC per VSI.
2) Allows a VSI to reconfigure its Tx queues during runtime.
3) Synchronizes the Tx scheduler update operations using locks.

This patch configures the VSIs to be able to send and receive
packets by doing the following:
1) Initialize flexible parser to extract and include certain
fields in the Rx descriptor.
2) Add Tx queues by programming the Tx queue context (implemented in
ice_vsi_cfg_txqs). Note that adding the queues also enables (starts)
the queues.
3) Add Rx queues by programming Rx queue context (implemented in
ice_vsi_cfg_rxqs). Note that this only adds queues but doesn't start
them. The rings will be started by calling ice_vsi_start_rx_rings on
interface up.
4) Configure interrupts for VSI queues.
5) Implement ice_open and ice_stop.

This patch adds code to continue the initialization flow as follows:
1) Get PHY/link information and store it
2) Get default scheduler tree topology and store it
3) Get the MAC address associated with the port and store it

This patch adds to the initialization flow by getting switch
configuration, scheduler configuration and device capabilities.
Switch configuration:
On boot, an L2 switch element is created in the firmware per physical
function. Each physical function is also mapped to a port, to which its
switch element is connected. In other words, this switch can be visualized
as an embedded vSwitch that can connect a physical function's virtual
station interfaces (VSIs) to the egress/ingress port. Egress/ingress
filters will be eventually created and applied on this switch element.
As part of the initialization flow, the driver gets configuration data
from this switch element and stores it.
Scheduler configuration:
The Tx scheduler is a subsystem responsible for setting and enforcing QoS.
As part of the initialization flow, the driver queries and stores the
default scheduler configuration for the given physical function.
Device capabilities:
As part of initialization, the driver has to determine what the device is
capable of (ex. max queues, VSIs, etc). This information is obtained from
the firmware and stored by the driver.
