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() Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
