2.17.1
Configure first lane to PCIe, the second lane to USB and the last two lanes
to eDP. Also, add sub-nodes to SERDES0 DT node to represent SERDES0 is
connected to PCIe.

2.17.1
The board uses lane 1 of SERDES for USB. Set the mux
accordingly.
The USB controller and EVM supports super-speed for USB0
on the Type-C port. However, the SERDES has a limitation
that upto 2 protocols can be used at a time. The SERDES is
wired for PCIe, eDP and USB super-speed. It has been
chosen to use PCIe and eDP as default. So restrict
USB0 to high-speed mode.

J721S2 has an OSPI NOR flash on its SOM connected the OSPI0 instance and a
QSPI NOR flash on the common processor board connected to the OSPI1
instance. Add support for the same
