[PATCH 2/6] dt-bindings: clock: add DDR3 standard speed bins.

[Enric Balletbo i Serra <enric.balletbo@collabora.com>]

DDR3 SDRAM Standard (JESD79-3F) defines some standard speed bins for
DDR3 memories. The devfreq/rk3399_dmc.txt binding refers to this file
which does not exist, so add a ddr.h file with the standard speed bins
for DDR3.

Fixes: c1ceb8f7c167 (Documentation: bindings: add dt documentation for rk3399 dmc)
