[PATCH] ppc32: Modify Freescale MPC52xx IRQ mapping to _not_ use irq 0

Browse Source 
AFAIK IRQ number 0 is a perfectly valid IRQ number.  But it seems there are
numerous places where it's considered to be invalid or "no irq" value.  Since
that value is problematic, the IRQ mapping is changed to not use it.
