[U-Boot] [PATCH v2] ARM: dt: zynq: Add labels to cpu nodes to allow overriding OPPs.

[Moritz Fischer]

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.

Ok, since I fatfingered v1 ... this one with right subject

Changes from v1: None

Sorry 'bout the noise,

Moritz
