Kumar Gala 957e263120 drivers: gpio: Update drivers to use devicetree Kconfig symbol 
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.

Kumar Gala bb03af637c drivers: gpio: remove unused HAS_DTS_GPIO Kconfig symbol 
All the gpio drivers are based on devicetree and thus we always set
HAS_DTS_GPIO, thus we don't need this Kconfig option anymore.  Remove
uses as its safe to assume DTS is supported for GPIO.
