[U-Boot] [PATCH v2 2/6] dm: x86: Set up interrupt routing from interrupt_init()

Tue Jan 19 04:39:08 CET 2016
At present interrupt routing is set up from arch_misc_init(). We can do it
a little later instead, in interrupt_init().
This removes the manual pirq_init() call. Where the platform does not have
an interrupt router defined in its device tree, no error is generated. Some
platforms do not have this.
Drop pirq_init() since it is no-longer used.
