xive: An extra '0x' prefix when printing hex values in the trace.

Host environment

• Operating system: Arch Linux
• OS/kernel version: 5.13.9
• Architecture: x86_64
• QEMU flavor: qemu-system-ppc64
• QEMU version: QEMU emulator version 6.0.91 (v6.1.0-rc1-87-g2cd9e2bd)
• QEMU command line:

  qemu-system-ppc64 -M powernv9 -trace enable=xive_*

Emulated/Virtualized environment

• Operating system: In-built skiboot is sufficient.
• OS/kernel version:
• Architecture: ppc64le

Description of problem

The trace functions corresponding to the functions below print certain parameters with a double "0x" prefix, i.e., with "0x0x".

• xive_source_esb_read
• xive_source_esb_write
• xive_tctx_tm_write
• xive_tctx_tm_read

Steps to reproduce

1. Execute the command line on a terminal
2. Watch the terminal for the output.
