[PATCH] kernelparams: detect if and which parameter parsing enabled irq's

The parsing of some kernel parameters seem to enable irq's at a stage that
irq's are not supposed to be enabled (Particularly the ide kernel parameters).

Having irq's enabled before the irq controller is initialized might lead to a
kernel panic.  This patch only detects this behaviour and warns about wich
parameter caused it.
