Most drivers need to set constraints on the buffer alignment for async tx
operations. However, even though it is documented, some drivers either use
a defined constant that is not matching what the alignment variable expects
(like DMA_BUSWIDTH_* constants) or fill the alignment in bytes instead of
power of two.
Add a new enum for these alignments that matches what the framework
expects, and convert the drivers to it.

The code here is checking for IS_ERR() but devm_ioremap() returns NULL
on error and not an error pointer.

We put 9 characters into the 8 character name[] array. Let's make the
array bigger and change the sprintf() to snprintf().
