drm/xe: fix build warning with CONFIG_PM=n

The 'runtime_status' field is an implementation detail of the
power management code, so a device driver should not normally
touch this:

drivers/gpu/drm/xe/xe_pm.c: In function 'xe_pm_suspending_or_resuming':
drivers/gpu/drm/xe/xe_pm.c:606:26: error: 'struct dev_pm_info' has no member named 'runtime_status'
  606 |         return dev->power.runtime_status == RPM_SUSPENDING ||
      |                          ^
drivers/gpu/drm/xe/xe_pm.c:607:27: error: 'struct dev_pm_info' has no member named 'runtime_status'
  607 |                 dev->power.runtime_status == RPM_RESUMING;
      |                           ^
drivers/gpu/drm/xe/xe_pm.c:608:1: error: control reaches end of non-void function [-Werror=return-type]

Add an #ifdef check to avoid the build regression.
