spi: dw-mid: change magic numbers to the constants
Instead of using magic numbers in the code we create a bit map definition of the DMACR register and use it. There is no functional change. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Mark Brown <broonie@kernel.org>
