[Skiboot] [PATCH 22/33] interrupts: LPC is always an interrupt controller

[Benjamin Herrenschmidt]

Whether we have Naples or not, the "interrupts" properties
of the child of the LPC node are always in the LPC interrupt
number space, and so should always have the LPC controller as
their interrupt controller.
