rapidio/tsi721: modify PCIe capability settings
Modify initialization of PCIe capability registers in Tsi721 mport driver:
- change Completion Timeout value to avoid unexpected data transfer
aborts during intensive traffic.
- replace hardcoded offset of PCIe capability block by making it use the
common function.
This patch is applicable to kernel versions starting from 3.2-rc1.
