[PATCH v2 2/5] dmaengine: ti: omap-dma: fix notifier leak in remove

[Rosen Penev]

The notifier may be registered for needs_busy_check (omap2420) rather than
may_lose_context (omap3). The remove path only checks may_lose_context,
leaving the notifier registered during driver removal. Check both flags.
