Vlad Zagorodniy 02a5a08a6c [platforms/drm] Rework ScopedDrmPointer
Summary:
Currently there is no any good reason for keeping ScopedDrmPointer;
providing our own deleter for QScopedPointer would make more sense.

Given that we already have type that acts as a scoped pointer for drm
objects we can improve it a bit and make simpler, e.g.

    DrmScopedPointer<drmModeConnector> connector;

is much simpler than

    ScopedDrmPointer<_drmModeConnector, &drmModeFreeConnector> connector;
