Enable mcu domain pinmux by default to be able to access mcu domain
peripherals from main domain.
This also makes it consistent with the rest of the k3 platforms where
mcu domain pinmux is enabled by default.

Add Error Signaling Module (ESM) instances in MCU and MAIN domains,
set ESM interrupt sources for rti as per TRM [0] 10.4 Interrupt
Sources.
Add comments to describe what interrupt sources are routed to ESM
modules.

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).

On AM62ax there are no hardware interrupts routed to A53 GIC
interrupt controller for MCU MCAN IPs, so MCU MCAN nodes were
omitted from MCU dtsi.
Timer polling was introduced in commits [1][2] enabling 3x MCAN
on AM62ax, so now add MCU MCAN nodes to the mcu dtsi for the Cortex A53.

Similar to commit 3308a31c50 ("arm64: dts: ti: k3-am62: Add general
purpose timers for am62"), there are 12 general purpose timers on am62a7
split between 8 in main and 4 in mcu domains. The 4 in mcu domain do not
have interrupts that are routable to a53.
We configure the timers with the 25 MHz input clock by default as the
32.768 kHz clock may not be wired on the device. We leave the MCU domain
timers clock mux unconfigured, and mark the MCU domain timers reserved.
The MCU domain timers are likely reserved by the software for the ESM
module.

The AM62A SoC belongs to the K3 Multicore SoC architecture platform that
can run edge AI applications with Video/Vision processing. This provides
advanced system integration with high security support to enable a broad
set of applications in industrial/automotive markets such as, driver
monitoring, machine vision, smart camera, eMirror, front camera,
robotics, and building automation.
Some highlights of AM62A SoC are:
* Quad-Cortex-A53s (running up to 1.4GHz) in a single cluster. Dual/Single
core variants are provided in the same package to allow HW compatible
designs.
* One Device manager Cortex-R5F for system power and resource management, and
one Cortex-R5F for Functional Safety or general-purpose usage.
* One AI accelerator (up to 2 TOPS), using one C7x256V DSP w/Matrix Multiplier
accelerator (MMA) for Deep Learning usage.
* VPAC3L(Vision Pre-processing Accelerator), providing 12-bit ISP up to
315MPixel/s RGB+IR support, and Noise Filter for improved integrated imaging
and vision image processing.
* H.264/H.265 Video Encode/Decode. + Motion JPEG encode
* Display support, providing 24-bit RBG parallel interface up to 200MHz pixel
clock support for 2K display resolution.
* Integrated Giga-bit Ethernet switch supporting up to a total of two external
ports (TSN capable).
* 9xUARTs, 5xSPI, 6xI2C, 2xUSB2, 3xCAN-FD, 3x eMMC and SD, GPMC for NAND/FPGA
connection, OSPI memory controller, 3x McASP for audio, 1x CSI-RX-4L for
Camera, eCAP/eQEP, ePWM, among other peripherals.
* Dedicated Centralized Hardware Security Module with support for secure boot,
debug security and crypto acceleration and trusted execution environment
* One 32 bit DDR Subsystem that supports LPDDR4, DDR4 memory types.
* Multiple low power modes support, ex: Deep sleep, Standby, MCU-only, enabling
battery powered system design.
