Input: wistron_btns - use pm_sleep_ptr() to allow removal of ifdef CONFIG_PM guards
As the guards only apply to suspend and resume, #ifdef CONFIG_PM_SLEEP
would have been a tighter protection. As pm_sleep_ptr() lets the compiler
see the protected ops structure and callbacks but also lets the compiler
remove it as unused code if !CONFIG_PM_SLEEP this allows the #ifdef
guards to be removed, slightly simplifying the resulting code.

It seems likely that DEFINE_SIMPLE_DEV_PM_OPS() would work here but
I'd prefer not to make that change unless someone can confirm that the
extra callbacks registered will have no unwanted side effects in this
driver.
