ssb: Clear RETRY_TIMEOUT in PCI Configuration for normal devices
MMIO log traces obtained using the Broadcom wl hybrid driver show that the RETRY_TIMEOUT register (0x41) in PCI configuration space is cleared if non-zero. Similar code found in other drivers such as ipw2100 show this operation is needed to keep PCI Tx retries from interfering with C3 CPU state. There are no known cases where omission of this code has caused a problem, but this patch is offered just in case such a situation occurs.
