The SERDES0 and SERDES1 instances of SERDES on J722S are single lane
SERDES which are individually muxed across different peripherals.
LANE0 of SERDES0 is muxed between USB and CPSW while LANE0 of SERDES1 is
muxed between PCIe and CPSW.
Define the lane-muxing macros to be used as the idle state values.

Modify license to include dual licensing as GPL-2.0-only OR MIT
license for SoC and TI evm device tree files. This allows for Linux
kernel device tree to be used in other Operating System ecosystems
such as Zephyr or FreeBSD.
While at this, update the GPL-2.0 to be GPL-2.0-only to be in sync
with latest SPDX conventions (GPL-2.0 is deprecated).
While at this, update the TI copyright year to sync with current year
to indicate license change.

Lanes 0 and 2 of the J721S2 SerDes WIZ are reserved for USB type-C
lane swap. Update the macro definition for it.

The DTS uses constants for SERDES MUX idle state values which were earlier
provided as bindings header. But they are unsuitable for bindings.
So move these constants in a header next to DTS.
Also add J784S4 SERDES4 lane definitions which were missed earlier.
