When devm_ioremap_resource() fails, a clear enough error message will be
printed by its subfunction __devm_ioremap_resource(). The error
information contains the device name, failure cause, and possibly resource
information.
Therefore, remove the error printing here to simplify code and reduce the
binary size.

The LogiCVC display hardware block comes with GPIO capabilities
that must be exposed separately from the main driver (as GPIOs) for
use with regulators and panels. A syscon is used to share the same
regmap across the two drivers.
Add a minimalistic GPIO driver to drive these GPIOs, using a syscon
regmap when available.
