Add MSTP port state registers for STP

Browse Source 
Each register holds the STP port state for one Forwarding ID (FID),
of which there 16 can be used by the RTL8372. The mapping between
FID and VLAN is done in the VLAN table. This allows the SoC
to maintain 16 different MSTP states.

In the register 2 bits per port are used to designate the following
(R)STP states
00 disable, 01 blocking, 10 learning, 11 forwarding
The STP listening state is not available.
