compat: handle pci suspend/resume on kernel 2.6.29

Before kernel 2.6.29, we use compat_pci_{suspend,resume}
and not the SIMPLE_DEV_PM_OPS, which include the code for
PCI device handling. For 2.6.30 and higher, the core PCI
code includes the device handling.

That leaves 2.6.29 as the odd one out and causes suspend
and resume to fail. Fix it by including the PCI device
handling code in the definition of SIMPLE_DEV_PM_OPS for
that kernel version.
