[PATCH 01/10] drm/tests: Stop using deprecated dev_private member on drm_framebuffer tests

[Carlos Eduardo Gallo Filho]

The dev_private member of drm_device is deprecated and its use should
be avoided. Stop using it by embedding the drm_device onto a mock struct
with a void pointer like dev_private, using it instead.
