On SONiC T1 cisco 8101 HwSku, the speed changes are done from 400G to 100G needs to be supported on 400G ports.
To enable this, along with speed change the port lanes need to be changed. This PR has the changes to update the port lanes when such speed change happens.
Basically if Banwidth in minigraph.xml intends to enable a 100G speed on a 400G port, then the appropriate lane change and speed change needs to be invoked in mingraph parser
Example if port_config.ini dicatates the speed to be 400G and minigraph has 100G speed, then this changeneeds to be accommodated

These platforms today have 400g port with 8 serdes lines, and 100g will operate with 4 serdes lane. When the port speed changes from 400G to 100G the first 4 lanes will be used for 100G port.
