[PATCH v2 0/4] amba: Properly handle device probe without IRQ domain

[Kefeng Wang]

Patch 1~3 make some cleanup, and patch 4 use of_irq_get() instead of 
irq_of_parse_and_map() to get irq number, return -EPROBE_DEFER if the irq
domain is not yet created, and move irq obtain into amba_probe, the driver 
defer probe will properly to handle this error.

V2:
- add new patch to kill irq sysfs file, suggested by Rob.
- move irq obtain from amba_device_add() to amba_probe(), suggested by Saravana.
  (As Saravana said, it will use a new mechanism to deal with the defer probe
   when amba device add and drop the amba specific deferring code, see[1])
- add Rob Reviewed-by to patch 1/2, no patch4 due to patch4 is changed
