[PATCH v2 1/3] MIPS: OCTEON: Add semaphore to serialize bootbus accesses.

From: David Daney 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
