ARM: tegra: Use DT /cpu node to detect number of CPU core
SCU based detection only works with Cortex-A9 MP and it doesn't support ones with multiple clusters. The only way to detect number of CPU core correctly is with DT /cpu node. Tegra SoCs decided to use DT detection as the only way and to not use SCU based detection at all. Even if DT /cpu node based detection fails, it continues with a single core Signed-off-by: Hiroshi Doyu <hdoyu@nvidia.com> Signed-off-by: Stephen Warren <swarren@nvidia.com>
