In order to boot the secondary CPUs on Armada 375, we need to set the boot address of these CPUs, through a register part of the System Controller (this deviates from the Armada XP design, where the boot address was defined using a register part of the PMSU unit). Therefore, this commit adds a new helper function in the System Controller driver to set the secondary CPU boot address. Moreover, it moves the System Controller initialization as an early_initcall(), since arch_initcall() is too late for an SMP-related initialization.
