Add a new SERDES driver for TI's AM654x SoC which configures
the SERDES only for PCIe. Support fo USB3 will be added later.
SERDES in am654x has three input clocks (left input, externel reference
clock and right input) and two output clocks (left output and right
output) in addition to a PLL mux clock which the SERDES uses for Clock
Multiplier Unit (CMU refclock).
The PLL mux clock can select from one of the three input clocks.
The right output can select between left input and external reference
clock while the left output can select between the right input and
external reference clock.
The driver has support to select PLL mux and left/right output mux as
specified in device tree.
