[PATCH]: [MPC5200] Fix lite5200b suspend/resume

[Tim Yamin]

Hi,

Suspend/resume ("echo mem > /sys/power/state") does not work for me
with vanilla kernels -- the system does not suspend correctly and just
hangs. The attached patch fixes this so suspend/resume works:

1) of_iomap does not map the whole 0xC0000 of the MPC5200 for me, so
saving registers does not work. Maybe this is just a bug in my DTB? Or
is this an of_iomap bug?
2) PCI registers need to be saved and restored. Would it make sense to
move struct mpc52xx_pci out of mpc52xx_pci.c and into a header?

If somebody else with a lite5200B board could do some testing this
would be appreciated as would comments on the above two issues.

Thanks,

Tim
