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.
