[pushed] [spu] Fix "info spu event" output formatting

[Ulrich Weigand]

Hello,

the formatting of the output of the "info spu event" command changed, causing
spurious test suite failures.  Use phex instead of phex_nz to get back the
expected format, and fix emission of new line characters.

Tested on spu-elf, pushed to mainline.

Bye,
Ulrich
