[PATCH] interrupt-mapping: Fix parent interrupt specifier description

[Stephen Boyd <stephen.boyd-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>]

The number of cells here is not dictated by the #interrupt-cells
property of this node, but the same property in the interrupt
parent. This looks like a copy/paste mistake from child interrupt
specifier.

    parent interrupt specifier
        The interrupt specifier in the parent domain. The number of 32-bit
        cells required to specify this component is described by the
