[Add mpc5121 support PATCHES v3 0/8]

[John Rigby]

This is a new improved set of patches based on the
comments that I received in response to the previous set.

Changes since v2:

1/8 Add-IPIC-config-option.patch
2/8 Add-mpc512x-ipic-support.patch
    No changes.  These two are in galak's queue for submission.

3/8 Basic-Freescale-MPC512x-support.patch
    Added missing of_put_node as pointed out by Stephen Rothwell
    Added Acked-by: Grant Likely <grant.likely at secretlab.ca>

4/8 Device-tree-for-MPC5121-ADS.patch
    Made changes suggested by Grant Likely

5/8 Separate-MPC52xx-PSC-FIFO-registers-from-rest-of-PSC.patch
6/8 Cleanup-checkpatch.pl-problems-in-mpc52xx_uart.c.patch
    No changes.  Grant is picking up these patches

7/8 Factor-out-52xx-dependencies-from-52xx-psc-driver.patch
    No changes.  No comments received.  Too ugly to comment?

8/8 Add-MPC512x-support-to-MPC52xx-psc-driver.patch
    Added IRQF_SHARED to flags passed to request_irq because
    on 5121 all PSCs use the same irq.  This should not break
    anything on 5200.
