phy: keystone: serdes driver for gbe 10gbe and pcie

On TI's Keystone platforms, several peripherals such as the
gbe ethernet switch, 10gbe ethernet switch and PCIe controller
require the use of a SerDes for converting SoC parallel data into
serialized data that can be output over a high-speed electrical
interface, and also converting high-speed serial input data
into parallel data that can be processed by the SoC.  The
SerDeses used by those peripherals, though they may be different,
are largely similar in functionality and setup.

This patch provides a SerDes phy driver implementation that can be
used by the above mentioned peripheral drivers to configure their
respective SerDeses.

The SerDes IP is owned by a 3rd party and this patch no comments
as recommended by the vendor. Also the license header used in the
file is in accordance with the vendor's recommendation of using
BSD license for the driver file.
