No, we don't know if the BD ring is in MURAM or main memory as it is

The above code would only be used if the BD is in MURAM.  The "if 
bd_mem_part == MEM_PART_MURAM" would stay.

If the BD ring can be in main memory, then I don't think we should be 
using a function called "iopa" to get its physical address.  It's 
conceivable that one day, iopa() will only work on memory that's been 
ioremap'ed.
