Tegra currently relies on the SCU to determine the number of CPU
cores, and also hard-codes the SCU physical address.
This series adds a /cpus node to the Tegra device tree, and updates
the code to rely solely on that to determine the CPU count. A new
API is introduced to query for the existence of SCU registers, and the
SCU register address. Tegra and OMAP2 are converted to use these new
APIs.
This pull request is based on a merge of v3.8-rc3, and arm-soc's
depends/rmk-perf branch.
