clocksource/drivers/ingenic-ost: Define pm functions properly in platform_driver struct

Commit ca7b72b5a5f2 ("clocksource: Add driver for the Ingenic JZ47xx OST")
adds the struct platform_driver ingenic_ost_driver, with the definition of
pm functions under the non-existing config PM_SUSPEND, which means the
intended pm functions were never actually included in any build.

As the only callbacks are .suspend_noirq and .resume_noirq, we can assume
that it is intended to be CONFIG_PM_SLEEP.

Since commit 1a3c7bb08826 ("PM: core: Add new *_PM_OPS macros, deprecate
old ones"), the default pattern for platform_driver definitions
conditional for CONFIG_PM_SLEEP is to use pm_sleep_ptr().

As __maybe_unused annotations on the dev_pm_ops structure and its callbacks
are not needed anymore, remove these as well.
