dmaengine: dw: revisit data_width property
There several changes are done here:
- Convert the property to be in bytes
Besides that this is a common practice for such property, the use of a value
in bytes much more convenient than handling the encoded one.
- Rename data_width to data-width in the device tree bindings
The change leaves the support for the old format as well just in case someone
will use a newer kernel with an old device tree blob.
- While here, replace dwc_fast_ffs() by __ffs()
