Device drivers should not access MMIO registers through hardcoded platform specific address constants. Instead, we can pass the MMIO token to the spear clock driver in the initialization routine to contain that knowledge in the platform code itself. Ideally, the clock driver would use of_iomap() or similar to get the address, and that can be used later, but for now, this is the minimal change.
