Masahiro Yamada 2071f149e5 ARM: uniphier: add functions to get SoC model/revision
We sometimes have to implement different code depending on the SoC
revision.  This commit adds functions to get the model/revision
number.

Note:
  Model number: incremented on major changes of the SoC
  Revision number: incremented on minor changes of the SoC

The "Model 2" exists for PH1-sLD3, ProXstream2/PH1-LD6b.
