[PATCH] mips: DVH fixes

 o Make CONFIG_SGI_PARTITION the default for those systems where firmware or
   host OS require it.
 o Check earlier for DVH aka SGI partitions to avoid confusing them with an
   MSDOS partition.
 o Detect RAID partitions on IRIX volumes.  Caveat: this uses one of the
   officially unused partition types which are not recogniced by the IRIX or
   RISC/os tools.  Doesn't seem to matter but should be mentioned for
   completeness.
