[Patch V4 18/42] ce4100, irq: do not set legacy_pic to null_legacy_pic

2014-06-09 Thread Jiang Liu 
Intel CE4100 platforms has i8259 legacy interrupt controllers, so don't
set legacy_pic to null_legacy_pic in late booting stage because we need
legacy_pic to mask i8259 pins when enabling IOAPIC pins for safety.
