x86: Move lapic_setup() call into init_bsp()
Currently lapic_setup() is called before calling mp_init(), which
then calls init_bsp() where it calls enable_lapic(), which was
already enabled in lapic_setup(). Hence move lapic_setup() call
into init_bsp() to avoid the duplication.

x86: Move MP initialization codes into a common place
Most of the MP initialization codes in arch/x86/cpu/baytrail/cpu.c is
common to all x86 processors, except detect_num_cpus() which varies
from cpu to cpu. Move these to arch/x86/cpu/cpu.c and implement the
new 'get_count' method for baytrail and cpu_x86 drivers. Now we call
cpu_get_count() in mp_init() to get the number of CPUs.

x86: Add multi-processor init
Most modern x86 CPUs include more than one CPU core. The OS normally requires
that these 'Application Processors' (APs) be brought up by the boot loader.
Add the required support to U-Boot to init additional APs.
