    compat: handle pci suspend/resume on kernel 2.6.29

The functions for pci suspend and resume are now created by
compat_pci_suspend and compat_pci_resume and then used by
SIMPLE_DEV_PM_OPS. This way attributes like static, const and so on are
forwarded in the struct dev_pm_ops define on all kernel versions.

In addition this patch adds an own SIMPLE_DEV_PM_OPS() for kernel
2.6.32 overwriting the original, because in kernel 2.6.32 const is
needed for struct dev_pm_ops in pci drivers.

This is based on work done by Johannes Berg.
