soc: samsung: chipid: Remove the regmap lookup error log

In commit 40d8aff614f7 ("soc: samsung: chipid: Convert exynos-chipid
driver to use the regmap API") of_find_compatible_node() call was
substituted with syscon_regmap_lookup_by_compatible() but also an error
log was added for case where lookup fails. On multiplatform the lookup
will always fail on any non-samsung device so the log is incorrect.
Remove the error log and just return an error code from
syscon_regmap_lookup_by_compatible() which internally calls
of_find_compatible_node().
