X-Git-Tag: upstream/snapshot3+hdmi~17631^2~19

m68knommu: remove unecessary interrupt level setting in ColdFire 520x setup

The new code for the interrupt controller in the ColdFire 520x takes
care of all the interrupt controller setup. No manual config of the
level registers (ICR) is required by the  platform device setup code.
So remove it.
