mfd: intel-lpss: Revert "Add missing check for platform_get_resource"

This reverts commit d918e0d5.

The commit in question does not fix anything and only introduces
a duplication in the code. The main intel_lpss_probe() performs
all necessary checks.

While at it and in order of avoiding similar patches to come, add
a comment.
