2.25.1
From: Raju Rangoju <Raju.Rangoju@amd.com>
Yellow Carp Ethernet devices use the existing PCI ID but
the window settings for the indirect PCS access have been
altered. Add the check for Yellow Carp Ethernet devices to
use the new register values.

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.
