[PATCH] drm/xe/xe_ggtt: No need to use xe_pm_runtime_get_noresume

[Ashutosh Dixit]

Switching from xe_device_mem_access_get/put to xe_pm_runtime_get/put
results in the following WARNING in xe_oa:

[11614.356168] xe 0000:00:02.0: Missing outer runtime PM protection

There seems to be no reason to use xe_pm_runtime_get_noresume in xe_ggtt
functions. Just use xe_pm_runtime_get.
