PM: sleep: Fix symbol export for _SIMPLE_ variants of _PM_OPS()

[ Upstream commit 8d74f1da776da9b0306630b13a3025214fa44618 ]

Currently EXPORT_*_SIMPLE_DEV_PM_OPS() use EXPORT_*_DEV_PM_OPS() set
of macros to export dev_pm_ops symbol, which export the symbol in case
CONFIG_PM=y but don't take CONFIG_PM_SLEEP into consideration.

Since _SIMPLE_ variants of _PM_OPS() do not include runtime PM handles
and are only used in case CONFIG_PM_SLEEP=y, we should not be exporting
dev_pm_ops symbol for them in case CONFIG_PM_SLEEP=n.

This can be fixed by having two distinct set of export macros for both
_RUNTIME_ and _SIMPLE_ variants of _PM_OPS(), such that the export of
dev_pm_ops symbol used in each variant depends on CONFIG_PM and
CONFIG_PM_SLEEP respectively.

Introduce _DEV_SLEEP_PM_OPS() set of export macros for _SIMPLE_ variants
of _PM_OPS(), which export dev_pm_ops symbol only in case CONFIG_PM_SLEEP=y
and discard it otherwise.
