habanalabs/gaudi2: read F/W security indication after hard reset

F/W security status might change after every reset.

Add the reading of the preboot status to the hard reset sequence, which
among others reads this security indication.

As this preboot status reading includes the waiting for the preboot to
be ready, it can be removed from the CPU init which is done in a later
stage.
