target-arm: Add arm_boot_info secure_boot control
Adds the secure_boot boolean field to the arm_boot_info descriptor. This
fields is used to indicate whether Linux should boot into secure or non-secure
state if the ARM EL3 feature is enabled. The default is to leave the CPU in an
unaltered reset state. On EL3 enabled systems, the reset state is secure and
can be overridden by setting the added field to false.
