MIPS: Calculate proper ebase value for 64-bit kernels
The ebase is relative to CKSEG0 not CAC_BASE. On a 32-bit kernel they are the same thing, for a 64-bit kernel they are not. It happens to kind of work on a 64-bit kernel as they both reference the same physical memory. However since the CPU uses the CKSEG0 base, determining if a J instruction will reach always gives the wrong result unless we use the same number the CPU uses.
