Changes in v2:
- Change model name to FriendlyElec
- Enable SD UHS modes
- Add startup delay to SDIO regulator to improve
issues reported with some cards
- Fix PMIC interrupt pin
- Add pinctrl node for ethernet-PHY
- Fix various formatting issues

This label shows up in the kernel tree.
User space scripts don't like a space in a dir name for example.
Users don't like typing mixed SHIFT-capitals.

But yes, since the early Chromebook project in 2014 we agreed on
doing in Rockchip dts files:
