[PATCH 08/11] rockchip: pine64: pinephone-pro: Migrate to use IO-domain driver

[Jonas Karlman]

Switch to use the IO-domain driver to configure IO-domain based on
device tree instead of a setup_iodomain() function.

Signed-off-by: Jonas Karlman <jonas at kwiboo.se>

This should be runtime tested by someone with a pinephone-pro device.
All DT props and driver seem to be enabled and I expect the io_vsel to
be configured with correct value.
