Remove Istep 10.3 From IPL Flow

Istep 10.3 (host_set_voltages) has been moved to Istep 8.12
and needs to be no-oped. Executing host_set_voltages twice
causes crashes due to secureboot thinking we are trying to
skip an istep. Note that validateSecuritySettings that was
performed in 10.3 has now been moved to 10.4 (with the required
sub-routines).
