livetree: avoid assertion of orphan phandles with overlays 

Right now, check_interrupts_property fails with overlays, as the phandle
for the interrupt-parent can be orphan. Avoid this by allowing the orphan
node to pass the assert check.

The process_checks() call is also moved later during init sequence,
so that we can use the global variable generate_fixups to check if
we are compiling an overlay.
