Subject: [PATCH v1 6/6] net/axgbe: alter the port speed bit range

From: Selwin Sebastian <selwin.sebast...@amd.com>

Newer generation Hardware uses the slightly different port speed bit widths, so 
alter the existing port speed bit range to extend support to the newer 
generation hardware while maintaining the backward compatibility with older 
generation hardware.

The previously reserved bits are now being used which then requires the 
adjustment to the BIT values, e.g.:

Before:
   PORT_PROPERTY_0[22:21] - Reserved
   PORT_PROPERTY_0[26:23] - Supported Speeds

After:
   PORT_PROPERTY_0[21] - Reserved
   PORT_PROPERTY_0[26:22] - Supported Speeds

To make this backwards compatible, the existing BIT definitions for the port 
speeds are incremented by one to maintain the original position.
