The supply name in the driver is AVDD as is the name for the pin
on the datasheet, if you specify it as AVDD1 in device tree the
current driver will not load.

This appears to have been a copy and paste error from the wm8994
which has 2 AVDD supplies and I believe these docs were based
on. I would prefer to update the documentation to match what the
driver already expects rather than the other way around.
