up_dac_common: Increase version for new feature

Add support for DDS phase width greather than 16.
The software should read the DDS phase data width register and configure
the DDS init and increment registers accordingly, otherwise the obtained
DDS output frequency will not be the desired one for DDS phase width
different than 16.

DDS_incr = (f_out * 2^(phase_width) * clkratio)/f_if
