[PATCH v5 1/5] ARM: dts: da850: add cpu node and operating points to DT

[Bartosz Golaszewski]

From: David Lechner <da...@lechnology.com>

This adds a cpu node and operating points to the common da850.dtsi file.

All operating points above 300MHz are disabled by default.

Regulators need to be hooked up on a per-board basis.
