====================
dpll: Add support for phase adjustment granularity

Phase-adjust values are currently limited only by a min-max range. Some
hardware requires, for certain pin types, that values be multiples of
a specific granularity, as in the zl3073x driver.

Patch 1: Adds 'phase-adjust-gran' pin attribute and an appropriate
         handling
Patch 2: Adds a support for this attribute into zl3073x driver
====================
