Rob Herring afc3bca4cf dt-bindings: Use lower case hex in unit-addresses
DT unit addresses should be lower case hex. Fix all the
binding examples.

Converted with the following command from Krzysztof Kozlowski:

Marek Szyprowski 523d3de41f clk: samsung: exynos5433: Add support for runtime PM
Add runtime pm support for all clock controller units (CMU), which belong
to power domains and require special handling during on/off operations.
Typically special values has to be written to MUX registers to change
internal clocks parents to OSC clock before turning power off. During such
operation all clocks, which enter CMU has to be enabled to let MUX to
stabilize. Also for each CMU there is one special parent clock, which has
to be enabled all the time when any access to CMU registers is being done.

This patch solves most of the mysterious external abort and freeze issues
caused by a lack of proper parent CMU clock enabled or incorrect turn off
procedure.

Rob Herring 4da722ca19 dt-bindings: Remove "status" from examples
Pretty much any node can have a status property, so it doesn't need to
be in examples.

Converted with the following command and removed examples with SoC and
board specific splits:

git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d'
