[PATCH] powerpc/mm: Add translation mode information in /proc/cpuinfo

[Aneesh Kumar K.V]

With this we have on powernv and pseries /proc/cpuinfo reporting

timebase        : 512000000
platform        : PowerNV
model           : 8247-22L
machine         : PowerNV 8247-22L
firmware        : OPAL
translation     : Hash
