[PATCH] ARM: dts: imx: Adjust CPU nodes

[Fabio Estevam]

Make CPU nodes consistent throughout the i.MX dts files, which
also matches the description from ePAPR spec.

This also fixes the following W=1 warning in some cases:

Warning (unit_address_vs_reg): Node /cpus/cpu at 0 has a unit name, but no reg property
