drm/xe: Remove useless mem_access during probe
xe_pm_init is the very last thing during the xe_pci_probe(),
hence these protections are useless from the point of view
of ensuring that the device is awake.
Let's remove it so we continue towards the goal of killing
xe_device_mem_access.
v2: Adding more cases
v3: Provide a separate fix for xe_tile_init_noalloc return (Matt)
Adding a new case where display HDCP init calls which
are also called at display probe time.
