drm/imagination: Discard pm_runtime_put() return value

The Imagination DRM driver defines pvr_power_put() to pass the return
value of pm_runtime_put() to the caller, but then it never uses the
return value of pvr_power_put().

Modify pvr_power_put() to discard the pm_runtime_put() return value and
change its return type to void.

No intentional functional impact.

This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.
