AMD: Set the mask of MTRR according to CONFIG_CPU_ADDR_BITS
The high bits of mtrr mask are MBZ (Must be zero). Writing 1 to these bits will cause exception. So be carefull when spread this change. The supermicro/h8scm needs more work. Currently it is set as it was. We need to check if the F10 and F15 have different value.
