ARM: install HYP vectors at PBL and Barebox entry ...

If the CPU was already in HYP mode when entering the PBL, install a
simple trap handler to allow to get back from SVC to HYP before
switching to HYP mode.

As the vectors are part of the currently running binary, we need to
do the same setup when starting the real Barebox binary, as the PBL
setup vectors might get overwritten. To do this we trap into HYP mode
just before jumping to Barebox and then re-do the vector setup and
SVC switch as the first thing in Barebox proper.
