Staging: ipack/bridges/tpci200: Protect device registers with spinlock. Some of the device registers are accessed from both interrupt and non-interrupt context. To ensure proper read-modify-write modification of these registers we can not use the "global" tpci200 mutex. Instead a spin-lock is used.
