Add bindings and descriptions for the SolidRun i.MX8M Plus based System
on Module and various reference boards based on said module:
- CuBox-M
- HummingBoard Mate
- HummingBoard Pro
- HummingBoard Pulse
- HummingBoard Ripple
Signed-off-by: Josua Mayer <josua@solid-run.com>

Changes in v2:
- Removed invalid spidev (rohm,dh2228fv) node for mikrobus header spi
(Reported-by: Krzysztof Kozlowski <krzk@kernel.org>)
- Added Acked-by: Rob Herring (Arm) <robh@kernel.org> on bindings
- Added m.2 connector reset hog for hummingboard pulse (usb-3.0 only,
pulled low from u-boot)
- Link to v1: https://lore.kernel.org/r/20250614-imx8mp-sr-som-v1-0-3ca3269883c4@solid-run.com

They share a common designed based on the "Pulse" version, defined by various assembly options. The HummingBoard Pulse features: - 2x RJ45 Ethernet - 2x USB-3.0 Type A - HDMI connector - mini-HDMI connector - microSD connector - mini-PCI-E connector with SIM slot supporting USB-2.0/3.0 interfaces - M.2 connector with SIM slot supporting USB-2.0/3.0 interfaces - MIPI-CSI Camera Connector (not described without specific camera) - 3.5mm Analog Stereo Out / Microphone In Headphone Jack - RTC with backup battery The variants Mate and Ripple are reduced versions of Pulse. The HummingBoard Pro extends Pulse with PCI-E on M.2 connector.
