[PATCH] PM: runtime: add system sleep callbacks to EXPORT_*_RUNTIME_DEV_PM_OPS()

[Neel Bullywon]

DEFINE_RUNTIME_DEV_PM_OPS() sets pm_runtime_force_suspend() and
pm_runtime_force_resume() as system sleep callbacks via
_DEFINE_DEV_PM_OPS(), but the exported variants
(EXPORT_RUNTIME_DEV_PM_OPS, EXPORT_GPL_RUNTIME_DEV_PM_OPS,
EXPORT_NS_RUNTIME_DEV_PM_OPS, EXPORT_NS_GPL_RUNTIME_DEV_PM_OPS)
only set RUNTIME_PM_OPS() and omit SYSTEM_SLEEP_PM_OPS(). This
means drivers using the export macros do not get system sleep
support, contrary to what the documentation suggests.

Add SYSTEM_SLEEP_PM_OPS(pm_runtime_force_suspend,
pm_runtime_force_resume) to all four export variants to match the
behavior of DEFINE_RUNTIME_DEV_PM_OPS().

All current users of these macros are IIO drivers (bme680, bmp280,
kxsd9, mpl115, bmi088-accel) and none implement custom system sleep
callbacks, so this change is safe for all existing callers.
