nb/intel/nehalem: Don't run graphic init on S3 resume
The assumption is made that an ACPI aware an OS does not rely on firmware to initialize the display. TESTED on a Lenovo Thinkpad X201 with Linux 5.2, display still works after S3, more than 200ms in time saved (dropped from 411ms to 182ms in total in one test).
