net: lan966x: Add PGID_GP_START and PGID_GP_END

The first entries in the PGID table are used by the front ports while
the last entries are used for different purposes like flooding mask,
copy to CPU, etc. So add these macros to define which entries can be
used for general purpose.

net: lan966x: Add function lan966x_mac_ip_learn()

Extend mac functionality with the function lan966x_mac_ip_learn. This
function adds an entry in the MAC table for IP multicast addresses.
These entries can copy a frame to the CPU but also can forward on the
front ports.
This functionality is needed for mdb support. In case the CPU and some
of the front ports subscribe to an IP multicast address.

net: lan966x: Fix the vlan used by host ports

The blamed commit changed the vlan used by the host ports to be 4095
instead of 0.
Because of this change the following issues are seen:
- when the port is probed first it was adding an entry in the MAC table
with the wrong vlan (port->pvid which is default 0) and not HOST_PVID
- when the port is removed from a bridge, it was using the wrong vlan to
add entries in the MAC table. It was using the old PVID and not the
HOST_PVID

This patch fixes this two issues by using the HOST_PVID instead of
port->pvid.
