mmc: core: Switch to use pm_ptr() for mmc_host_class_dev_pm_ops
Currently, the mmc_host_class_dev_pm_ops and its callback
functions are wrapped in #ifdef CONFIG_PM_SLEEP to handle the
conditional compilation when PM support is disabled.
Replace this #ifdef usage with the standard pm_ptr() helpers. This
allows the compiler to automatically optimize away the unused code
paths when CONFIG_PM_SLEEP is not selected, resulting in cleaner and
more maintainable code.
