arm64: dts: ti: k3-am62a7: Add MIT license along with GPL-2.0

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 (and add it at least for one file which was
missing TI copyright).

arm64: dts: ti: k3-am62a7-sk: Add HDMI support

The DSS outputs DPI signals via its second video port (VP2). The DPI
output from DSS is 24 bits (RGB888) and is forwarded to an HDMI
transmitter (SIL9022) on the board.

Add pinmux info for DSS DPI output.

Add DT nodes for SIL9022 HDMI transmitter (TX), and the HDMI connector
on the AM62A7-SK platforms.

Additionally, connect the output of DSS (VP2) with input of the HDMI TX,
and the output of HDMI TX to the input of the HDMI connector.

The TLV320AIC3106 audio codec is interfaced on the i2c-1 bus. With the
default rate of 400Khz the i2c register writes fail to sync:

[ 36.026387] tlv320aic3x 1-001b: Unable to sync registers 0x16-0x16. -110

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.
