use I2C_INIT_PRIORITY as default for gpio chips,
that are on a i2c bus.
If childs have the same priority as their parents,
the init order is decided by the devicetree ordinals.
This ensures, that these childs are init after their parent.
Because of that gpio chips on a i2c bus can have the
same priority as the i2c controller.

This makes Kconfig logging options for this driver depending on whether
the driver is enabled or not.

Update gpio drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol
to expose the driver and enable it by default based on devicetree.
We remove 'depend on' Kconfig for symbols that would be implied by
the devicetree node existing.
