Jason Chen CJ 238d8bbaa2 reshuffle init_vm_boot_info
now only SOS need decide boot with de-privilege or direct boot mode, while
for other pre-launched VMs, they should use direct boot mode.

this patch merge boot/guest/direct_boot_info.c &
boot/guest/deprivilege_boot_info.c into boot/guest/vboot_info.c,
and change init_direct_vboot_info() function name to init_general_vm_boot_info().

in init_vm_boot_info(), depend on get_sos_boot_mode(), SOS may choose to init
vm boot info by setting the vm_sw_loader to deprivilege specific one; for SOS
using DIRECT_BOOT_MODE and all other VMS, they will use general_sw_loader as
vm_sw_loader and go through init_general_vm_boot_info() for virtual boot vm
info filling.

this patch also move spurious handler initilization for de-privilege mode from
boot/guest/deprivilege_boot.c to boot/guest/vboot_info.c, and just set it in
deprivilege sw_loader before irq enabling.
