soc/intel/baytrail,denverton_ns: Call setup_lapic()
A custom board with soc/intel/denverton_ns does not respond to
the keyboard and does not boot from the sata/USB disks.
Last post code 0x7b and the last line that is displayed at log
from SeaBIOS is:
All threads complete.
The issue is gone when adding setup_lapic() call to configure
EXTINT delivery of i8259 originated interrupts for the LAPIC.
Replicate call from other soc/ and make the call for both BSP
and AP CPUs.
Similar change was done for soc/intel/braswell in
commit b4f57bb3cac3ab29b9fa9c526ad4358faffb77a1.
