ARM: HYP/non-sec: move switch to non-sec to the last boot phase

Browse Source 
Having the switch to non-secure in the "prep" phase is causing
all kind of troubles, as that stage can be called multiple times.

Instead, move the switch to non-secure to the last possible phase,
when there is no turning back anymore.
