arm64: dts: ti: phycore*: Add MIT license along with GPL-2.0

Modify license to include dual licensing as GPL-2.0-only OR MIT
license for device trees belonging to PHYTEC Messtechnik GmbH and
PHYTEC America, LLC platforms. 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 copyright year to sync with current year
to indicate license change.

arm64: dts: ti: Unify pin group node names for make dtbs checks

Prepare for pinctrl-single yaml binding and unify pin group node names.

Let's standardize on pin group node naming ending in -pins. As we don't
necessarily have a SoC specific compatible property for pinctrl-single.
I'd rather not add a pattern match for pins somewhere in the name for all
the users.

Trying to add matches for pins-default will be futile as on the earlier
SoCs we've already seen names like pins-sleep, pins-idle, pins-off and so
on that would need to be matched.

And as the node is a pin group, let's prefer to use naming -pins rather
than -pin as more pins may need to be added to the pin group later on.

arm64: dts: ti: Add basic support for phyBOARD-Lyra-AM625

The phyCORE-AM62x [1] is a SoM (System on Module) featuring TI's AM62x SoC.
It can be used in combination with different carrier boards.
This module can come with different sizes and models for
DDR, eMMC, SPI NOR Flash and various SoCs from the AM62x family.

A development Kit, called phyBOARD-Lyra [2] is used as a carrier board
reference design around the AM62x SoM.

Supported features:
* Debug UART
* SPI NOR Flash
* eMMC
* 2x Ethernet
* Micro SD card
* I2C EEPROM
* I2C RTC
* GPIO Expander
* LEDs
* USB
