Subject: powerpc: 52xx: nop out unsupported critical IRQs

Currently, when booting MPC52xx based platforms, we get:

        mpc52xx_irqhost_map: invalid irq: virq=16, l1=0, l2=3
        irq: irq-16==>hwirq-0x3 mapping failed: -22
        [WARNing skipped]

The warning is wrong since the mapping itself is valid. However, there is no
support for that type of IRQ currently. Print a proper warning and bind the irq
to a no_irq chip.

Subject: powerpc/mpc5200: move lpbfifo node and fix its interrupt property

The LPB FIFO interrupt is a peripheral interrupt, thus its L1 cell
has to be 2 instead of 3. Fix it and while at it, move the lpbfifo
node to the common dtsi file.

This patch fixes the irqdomain warning:
