Moritz Fischer 720ba46e71 ARM: dt: zynq: Add labels to cpu nodes to allow overriding OPPs.
By adding labels to the cpu nodes in the dtsi, a dts that
includes it can change the OPPs by referencing the cpu0
through the label.

Masahiro Yamada 621a93e140 ARM: dts: zynq: describe SLCR as simple-mfd rather than simple-bus
Commit 9f56917ab8 ("dm: core: make simple-bus compatible to
simple-mfd") made possible to import the following commit:

Linux commit: bc5ba9b98435bf76d92e0954da1784695aa449f1

The SLCR (System-Level Control Registers) block is an MFD (Multi
Function Device) rather than a bus.

"simple-mfd" seems a more suitable compatible string than "simple-bus".

Zynq does not support voltage scaling and the CPU rail should always be

Masahiro Yamada 580a54c5d4 zynq: import zynq-7000.dtsi from Linux Kernel
Our current motivation is to use OF initialization for RAM and UART.
But adding full DTS would be helpful in future, for instance,
for OF configuration of Ethernet, MMC, USB, etc.

This commit imports arch/arm/boot/dts/zynq-7000.dtsi from Linux 3.15-rc5
and adjusts the license comment block for SPDX.
