x86: dt: Cleanup local apic setup

Up to now we force enable the local apic in the devicetree setup
uncoditionally and set smp_found_config unconditionally to 1 when a
devicetree blob is available. This breaks, when local apic is disabled
in the Kconfig.

Make it consistent by initializing device tree explicitely before
smp_get_config() so a non lapic configuration could be used as well.
To be functional that would require to implement PIT as an interrupt
host, but the only user of this code until now is ce4100 which
requires apics to be available. So we leave this up to those who need
it.
