[Qemu-ppc] [PATCH 6/9] target-ppc: Fix invalid SPR read/write warnings

[Alexander Graf]

From: Anton Blanchard <address@hidden>

Invalid and privileged SPR warnings currently print the wrong
address. While fixing that, also make it clear that we are
printing both the decimal and hexadecimal SPR number.

Before:

  Trying to read invalid spr 896 380 at 0000000000000714

After:

  Trying to read invalid spr 896 (0x380) at 0000000000000710
