Add the device tree for the QCS615-based Talos EVK platform. The
platform is composed of a System-on-Module following the SMARC
standard, and a Carrier Board.
The Carrier Board supports several display configurations, HDMI and
LVDS. Both configurations use the same base hardware, with the display
selection controlled by a DIP switch.
Use a DTBO file, talos-evk-lvds-auo,g133han01.dtso, which defines an
overlay that disables HDMI and adds LVDS. The DTs file talos-evk
can describe the HDMI display configurations.
The initial device tree includes support for:
- CPU and memory
- UART
- GPIOs
- Regulators
- PMIC
- Early console
- AT24MAC602 EEPROM
- MCP2515 SPI to CAN
- ADV7535 DSI-to-HDMI bridge
- DisplayPort interface

I really don't like the idea of describing two separate backlight
devices here. We have a single backlight on the panel, controlled by two
GPIOs. I think, using GPIO instead of a PWM is a sensible enough usecase
to let DT use two GPIOs in gpio-backlight (with corresponding changes to
the bindings and the driver).
