target-arm: Set CPU has_el3 prop during virt init

Adds setting of the CPU has_el3 property based on the virt machine
secure state property during initialization.  This enables/disables EL3
state during start-up.  Changes include adding an additional secure state
boolean during virt CPU initialization.  Also disables the ARM secure boot
by default.
