But In its_alloc_tables() function,

This patch set adds the driver of mbigen and binding document for Hisilicon
Mbigen chips.
Compared with previous version, this version changed much.

For peripheral devices which connect to mbigen,mbigen is a interrupt
controller. So, we create irq domain for each mbigen device and add
mbigen irq domain into irq hierarchy structure.
