[PATCH v2 00/11] gpio: msc313: Add gpio support for ssd20xd

This is a little series to add a compatible string for the Sigmastar
SSD201 and SSD202D to the msc313 gpio driver, add the specific offsets
for the pins on these chips, and then a bunch of DT wiring stuff so
that the LEDs on the M5 stack unitv2 work and it can control the
power switch for the USB connected.

Changes since v1:
- Add a fix for the led binding to squash the warning about the
activity trigger in the unitv2 dts.
- Fix up the regulator node names so they pass dtb check
