bootstrap: skip zero sized late_ram_regions

Browse Source 
On some platforms late_ram_regions are initialized to zero which
leads bootstrap to insert zero based/sized ram regions wich later caused
the following warning in core:

! unable to register RAM region base=0x0 size=0x0
! unable to exclude I/O range from RAM: base=0x0 size=0x0

Therefore, omitt adding zero sized regions to the boot info.

issue #5496
