HV: relocate SOS kernel before boot modules for SBL

Browse Source 
SBL would load multiboot modules to the maximum usable ram below 4GB, in this
case the SOS kernel would be failed to load because no room for kernel in
the range of end of modules and MEM_4G. So kernel must be relocated to the
range of MEM_1M and start of modules, or other appropriate place according
to modules layout.

Tracked-On: #6162
