Fix, Add support for the Power PC Program Priority Register

Commit r3189 had a typo in it.  In function LibVEX_GuestPPC64_initialise()
the value of  vex_state->guest_PSPB is initialized to 0x0.  The intention was
for it to be initialized to 0x100.  This commit fixes the typo.

The original commit message:

  Added the Program Priority Register (PPR), support to read and write it
  via the mfspr and mtspr instructions as well as the special OR instruction
  No Op instructions.  The setting of the PPR is dependent on the value in
  the Problem State Priority Boost register.  Basic support for this register
  was added.  Not all of the PSPB register functionality was added.

  This patch fixes bugzilla 352769.
