drm/vc4: Release runtime PM reference after binding V3D
The vc4_v3d_bind() function acquires a runtime PM reference via
pm_runtime_resume_and_get() to access V3D registers during setup.
However, this reference is never released after a successful bind.
This prevents the device from ever runtime suspending, since the
reference count never reaches zero.
Release the runtime PM reference by adding pm_runtime_put_autosuspend()
after autosuspend is configured, allowing the device to runtime suspend
after the delay.
