Add the GPU node for the Adreno 506 found on this family of SoCs. The
clock speeds are a bit different per SoC variant, SDM450 maxes out at
600MHz while MSM8953 (= SDM625) goes up to 650MHz and SDM632 goes up to
725MHz.

To achieve this, create a new sdm450.dtsi to hold the 600MHz OPP and
use the new dtsi for sdm450-motorola-ali.

If you remove all OPPs but this one, can the GPU still spit out pixels?
