This change adds a RC6 test for the MOCS. The MOCS registers are loaded
and saved as part of the RC6 cycle but not all the registers are
saved/restored. This tests that those registers are correctly restored.

This is duplicating code from igt_sysfs.c
PS: Not in the current tree. The code is based on code from
pm_rc6_residency.
Your tree is a couple of months out of date.
