drm/xe: Runtime PM wake on every IOCTL
Let's ensure our PCI device is awaken on every IOCTL entry.
Let's increase the runtime_pm protection and start moving
that to the outer bounds.
v2: minor typo fix and renaming function to make it clear
that is intended to be used by ioctl only. (Matt)
v3: Make it NULL if CONFIG_COMPAT is not selected.
