dmaengine: add dmaengine_get_cap_mask() and dmaengine_has_cap() helpers
Add two new inline helpers to query DMA channel capabilities without
directly accessing the internal dma_device pointer:
dmaengine_get_cap_mask(chan) - returns a const pointer to the
capability mask of the DMA device backing the channel.
dmaengine_has_cap(chan, tx_type) - returns true if the channel
supports the given transaction type.
These complement the existing dma_has_cap() macro which operates on
a dma_cap_mask_t directly.
