Subject: ACPI / PM: Combine two identical device resume routines
Git-commit: 63705c406a8adbd6f26691148b09d466dd4d8d2f
Patch-mainline: v4.15-rc1
References: fate#326249

Notice that acpi_dev_runtime_resume() and acpi_dev_resume_early() are
actually literally identical after some more-or-less recent changes,
so rename acpi_dev_runtime_resume() to acpi_dev_resume(), use it
everywhere instead of acpi_dev_resume_early() and drop the latter.
