David Daney 24d4e7f642 MIPS: OCTEON: Add semaphore to serialize bootbus accesses. 
Some hardware blocks attached to the OCTEON bootbus run asynchronously
to accesses from the CPUs.  These include MMC/SD host, CF(when using
DMA), and NAND controller.  A bus error, or corrupt data may occur if
a CPU is trying to access a bootbus connected device at the same time
the bus is running asynchronous operations.

To work around these problems we add this semaphore that must be
acquired before initiating bootbus activity.  Subsequent patches will
add users for this.
