Subject: [PATCH v2 1/3] genirq/irq_sim: Allow both one and two cell bindings

From: Wei Yongjun <weiyongjun1@...wei.com>

The IRQ simulator only support one cell binding now, this patch make it
works with either one or two cell bindings, where the cell values map
directly to the irq number and irq flags.
