drivers: i2c: Update drivers to use devicetree Kconfig symbol

Browse source 
Update i2c 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.
