[PATCH 22/26] drm: vboxvideo: Remove #ifdef guards for PM related functions

[Paul Cercueil]

Use the pm_sleep_ptr() macro to handle the .suspend / .resume callbacks.

This macro allows the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_SUSPEND is disabled, without having
to use #ifdef guards.

This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.
