powerpc/mpc85xx: Add revision properties in portal device tree node 'pme'
The 'fsl,pme-rev1' and 'fsl-pme-rev2' properties have been added to the pme portal node. This is required for software to determine which version of PME hardware is present and take appropriate actions. These properties are a direct reflection of the corresponding ccsr pme register value. Also removed unnecessary static global variables.
