[CORE] Improve SMP bootup sequence for supporting CPU hotplug in future.

This patch makes SMP bootup sequence very much like Linux kernel.

The code code requires: arch_smp_init_cpus(), arch_smp_prepare_cpus(), and arch_smp_start_cpu().

The arch_smp_init_cpus() is supposed to initizalize SMP control HW and update the cpu_possible mask based on possible CPUs.

The arch_smp_prepare_cpus() is supposed to prepare for SMP kicking and update the cpu_present mask based on actual HW CPUs present.

The arch_smp_start_cpu() is only for kicking a secondary CPU.

[ARM] arm32: Merge v7 mmu and v5 mmu to reduce redundancy.

This patch merges v7 mmu support and v5 mmu support to reduce redundancy.

The v7 mmu is backward compatible to v6 mmu so, the merged mmu support is actually for v5, v6 and v7 processors
