[PATCH] drm/imx: Remove unused field imx_drm_device.pipes

[Leonard Crestez]

This has been unused since commit 44b460cfe554 ("drm: imx: remove struct
imx_drm_crtc and imx_drm_crtc_helper_funcs")

Looking at the imx_drm_device struct it is only used to save the
drm_atomic_helper_suspend state. It seems like this could be replaced
with drm_mode_config_helper_suspend/resume and the entire struct
removed.

The only difference between imx_drm_suspend/resume and
drm_mode_config_helper_suspend/resume is that the latter also suspends
the fb_helper. This would be an improvement, right?
