asm-generic/mmiowb: Add generic implementation of mmiowb() tracking
In preparation for removing all explicit mmiowb() calls from driver code, implement a tracking system in asm-generic based loosely on the PowerPC implementation. This allows architectures with a non-empty mmiowb() definition to have the barrier automatically inserted in spin_unlock() following a critical section containing an I/O write.
