[00/16] Enable Power Modes Support for SAMA7D65 SoC

Message

From: Ryan Wanner <[e-mail]>

This patch set adds support for low power modes for the SAMA7D65 SoC and
the required components and changes for low power modes.

The series includes changes in the asm code to account for the addtional
clocks that are in this SoC.

The Device tree additions are to enable all the components needed to
keep the SoC in low power mode.

There are some DTB check warnings but that is due to the dt-binding not
in the correct .yaml file format.
