By switching AP wakeup from broadcast to one by one, we could
set correct stack for each AP and drop the temp stack used during

- enable NX feature in hypervisor:
1. Set 'XD' bit for all pages, including pages for guests
when initialize MMU tables in hypervisor.
2. remove 'XD' bit for pages that contain hypervisor instructions.
3. enable MSR EFER.NXE,which will enable page access restriction by
preventing instruction fetches form pages with XD bit set.
- remove "-Wl -z noexecstack" GCC flag option in hypervisor
Makefile as it would not affect stack attribute in hyervisor,
which setup stack itself, instead of by loader.

replace CPU_PAGE_SIZE with PAGE_SIZE
These two MACROs are duplicated and PAGE_SIZE is a more reasonable name.

Boot component prepares the very basic platform boot env. It finally call
into platform initilization entries:
- bsp_boot_init & cpu_secondary_init for start up
- or restore_s3_context for wakeup
this patch is the final one, it did some code clean up and move some definition
from vm0_boot.h to boot_context.h.
after this patch, the boot component include files:
arch/x86/boot/cpu_primary.S
arch/x86/boot/trampoline.S
arch/x86/boot/cpu_save_boot_ctx.S
arch/x86/boot/idt.S
boot/reloc.c
boot/include/reloc.h
include/arch/x86/boot/idt.h
include/arch/x86/boot/boot_context.h
