RealView: Move the SCU initialisation out of __v6_setup
This patch moves the SCU initialisation from __v6_setup to the smp_prepare_cpus() function as it relies on platform-specific settings. Changes to get_core_count() are mainly for allowing cleaner code with the upcoming PB11MPCore patches. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
