target/hppa: Wire up diag instruction to support BTLB

Browse source 
Wire up the hppa diag instruction to support Block-TLBs
when called with the 0x100 value.

The diag_btlb() helper function does all necessary steps
to emulate the PDC BTLB firmware function, which includes
providing BTLB info, adding a new BTLB, deleting a BTLB
and removing all BTLBs.
