cpu_dead calls arch_cpu_dead, cpu_do_idle calls arch_cpu_do_idle,
arch_cpu_dead and arch_cpu_do_idle are required to be implemented by
each architecture.

The following pcpu related interfaces are moved into common:
- common/cpu.c::start_pcpus
- include/common/cpu.h::get_pcpu_id
- include/common/cpu.h::set_current_pcpu_id
Their arch specific implementations are moved into arch/$(ARCH):
- arch/$(ARCH)/cpu.c::arch_start_pcpu
- include/arch/$(ARCH)/asm/cpu.h::arch_get_pcpu_id
- include/arch/$(ARCH)/asm/cpu.h::arch_set_current_pcpu_id
The following interface is moved into common:
- pcpu_set_current_state (from arch/x86/cpu.c -> common/cpu.c)
The following MACROs are moved into include/common/cpu.h:
- CPU_UP_TIMEOUT
- CPU_DOWN_TIMEOUT
- BSP_CPU_ID
- INVALID_CPU_ID

Extract common interface to include/lib/bits.h, and invoke the variant
implementation of arch.
Re-implement unlocked functions as C in common library.
Rename bitmap*lock() to bitmap*(), bitmap*nolock() to bitmap*non_atomic().

Move phys_cpu_num and pcpu_active_bitmap to common, which could be
only accessed by interfaces provided by smp.h.
v2->v3:
1. move ALL_CPUS_MASK/AP_MASK to common cpu.h
v1->v2:
1. preserve phys_cpu_num in x86 but implement arch_get_num_available_cpus()
to provide interface for common code to access.
2. change function name test_xx to check_xx
