[PATCH 6/6] drm/gma500: Remove unnecessary suspend/resume wrappers

[Hans de Goede]

The psb_runtime_suspend/resume/thaw/freeze/restore functions are all
just 1:1 wrappers around gma_power_suspend/_resume.

Drop these wrappers and use the DEFINE_RUNTIME_DEV_PM_OPS() macro to
define the dev_pm_ops struct.
