drm/nouveau: Rename acpi_work to hpd_work
We need to call drm_helper_hpd_irq_event() on resume to properly detect monitor connection / disconnection on some laptops. For runtime-resume (which gets called on resume from normal suspend too) we must call drm_helper_hpd_irq_event() from a workqueue to avoid a deadlock. Rename acpi_work to hpd_work, and move it out of the #ifdef CONFIG_ACPI blocks to make it suitable for generic work.
