2022-12-13Documentation: Add wake source info to device tree documentationRaul E Rangel
The device tree documentation was promoting using a GPIO wake event and a GPE wake event. We should only ever have one. This wasn't actually causing a problem because the wake bit was set on the `irq` property, but the IO-APIC can't actually wake the system, so it was a no-op. This change fixes up the markdown so it's formatted correctly, and also adds a section explaining what the different wake configurations are.

2022-09-23Documentation: split devicetree driver hookup into separate pageMatt DeVillier
Move the devicetree driver example into a separate page under the drivers category, and link to it from both the devicetree page and the drivers index page. This makes more sense from a grouping perspective and makes the info easier to find.
