Florian Fainelli 01ce18b311 dma-debug: introduce dma_debug_disabled
Add a helper function which returns whether the DMA debugging API is
disabled, right now we only check for global_disable, but in order to
accommodate early callers of the DMA-API, we will check for more
initialization flags in the next patch.
