Switch to use dev_err_probe() to simplify the error path and
unify a message template.
Using this helper is totally fine even if err is known to never
be -EPROBE_DEFER.
The benefit compared to a normal dev_err() is the standardized format
of the error code, it being emitted symbolically and the fact that
the error code is returned which allows more compact error paths.

Support for enabling the digital noise filter, and support for
configuring the noise filter stages (via the FILNUM register) and the
sampling interval (via the FILCLKSEL register) are related: a pin
supports either all or none of them. Hence simplify declaring digital
noise filter support for a pin by using a single feature flag instead of
three separate flags.
This patch removes the PIN_CFG_FILNUM and PIN_CFG_FILCLKSEL configuration
macros and renames PIN_CFG_FILONOFF to PIN_CFG_NF.
