ARM: tegra: smp: Add support for Cortex-A15 boot_secondary
Cortex-A15 does not have a memory-mapped SCU in the PERIPHBASE
aperture. Instead, the number of CPUs present is obtained from
the architectural L2 Cache Control (L2CTLR) register.
Enable HAVE_ARM_SCU only on platforms that have a memory-mapped
SCU and add the necessary conditionals to prevent access to the
memory-mapped SCU address range on platforms that don't.
