[POWERPC] Update xmon slb code
This adds a bit more detail to the xmon SLB output. When the valid
bit is set, this displays the ESID and VSID values, as well as
decoding the segment size -- 1T or 256M -- and displaying the LLP
bits. This supresses the output for any slb entries that contain only
zeros.
sample output from power6 (1T segment support):
00 c000000008000000 40004f7ca3000500 1T ESID= c00000 VSID= 4f7ca3 LLP:100

sample output from power5 (notice the non-valid but non-zero entries)
10 0000000008000000 00004fd0e077ac80 256M ESID= 0 VSID= 4fd0e077a LLP: 0

Tested on power5 and power6.
