dmaengine: add dmaengine_get_copy_align() and related alignment getter helpers
Add dmaengine_get_copy_align(), dmaengine_get_xor_align(),
dmaengine_get_pq_align(), and dmaengine_get_fill_align() inline
helpers to retrieve the alignment requirement of a DMA channel as
a power-of-2 exponent.
These complement the existing dmaengine_is_*_aligned() test helpers
by providing direct access to the alignment value, which is useful
when callers need to propagate or compare alignment constraints.
