v2 cover qcom_rpm: add support for IPQ8064 resources

This is a resend of the IPQ RPM support that Josh sent a while back. I've removed the regulator part because that has been done a different way now.

PATCH v2 1/2 mfd: devicetree: qcom_rpm: document IPQ8064 resources

From: Josh Cartwright <[email protected]>

The IPQ8064 SoC has several RPM-controlled resources, an NSS fabrick clock and four regulator resources. Provide definitions for them.

PATCH v2 2/2 mfd: qcom_rpm: add support for IPQ8064

In reply to Stephen Boyd

From: Josh Cartwright <[email protected]>

The IPQ8064 also includes an RPM following the same message structure as other chips. In addition, it supports a few new resource types to support the NSS fabric clocks and the SMB208/SMB209 regulators found on the reference boards.
