The Kconfig help text for the SN74HC595 driver refers to the device
as a "GPIO extender", which is inconsistent with the devicetree
binding file (ti,sn74hc595.yaml) that describes it as a "GPIO expander".

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.
