Subject: [PATCH v2 01/11] msm: Add CPU queries

Create runtime queries to distinguish the various MSM targets.
Although these would probably be better named soc_is..., use
cpu_is... to match convention in the rest of the kernel.

Hard code the tests based on config options for now.  When runtime
device detection is implemented, these can be made dynamic.
