drm/i915/pxp/mtl: intel_pxp_init_hw needs runtime-pm inside pm-complete

Browse source

In the case of failed suspend flow or cases where the kernel does not go
into full suspend but goes from suspend_prepare back to resume_complete,
we get called for a pm_complete but without runtime_pm guaranteed.

Thus, ensure we take the runtime_pm when calling intel_pxp_init_hw
from within intel_pxp_resume_complete.

v2: resume_complete and runtime_resume should abstract a common
    helper with different wakeref requirements. (Daniele)
