ps-clk-frequency is platform specific setting and shouldn't be the part

Remove unneeded address-cells form intc node because it is already setup
in parent node.
Add missing address-cells and size-cells to eth node to be shared for
every platform DTSes.

Use the new zynq binding for macb ethernet, since it will disable half
duplex gigabit like the Zynq TRM says to do. Also allow the compatible
cadence gem binding that won't disable half duplex but works otherwise.

Zynq is using Cadence IP where binding is documented in the Linux kernel
and there is no reason to use different binding.
Synchronize it.

Due to dependencies between timer and CPU frequency, only changes by
powers of two are allowed. The clocksource driver prevents other
changes, but with cpufreq and its governors it can result in being
spammed with error messages constantly. Hence, remove the 222 MHz OPP.

The Zynq UART is Cadence IP and the driver has been renamed accordingly.
Migrate the DT to use the new binding for the UART driver.

To silence the warning
cpufreq_cpu0: failed to get cpu0 regulator: -19
from the cpufreq driver regarding a missing regulator,
add a fixed regulator to the DT.
Zynq does not support voltage scaling and the CPU rail should always be
supplied with 1 V, hence it is added in the SOC-level dtsi.

Now zynq spi driver platform data is controlled by devicetree,
enable the status by saying "okay" on respective board dts to use
the devicetree generated platdata.
Ex:
&spi1 {
status = "okay";
};

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

This patch provides a basic fdt support for zynq u-boot.
zynq-7000.dtsi-> initial arch dts file
zynq-zed.dts -> initial zed board dts file
more devices should be added in subsequent patches.
u-boot build: once configuring of a board done
for building dtb with zynq-zed.dts as an input
zynq-uboot> make DEVICE_TREE=zynq-zed
Enabled CONFIG_OF_SEPARATE for building dtb separately.
There is a new binary called u-boot-dtb.bin which is a u-boot
with devicetree supported.
