powerpc: Use pr_warn instead of pr_warning

At some point, pr_warning will be removed so all logging messages use
a consistent <prefix>_warn style.

Update arch/powerpc/

Miscellanea:

o Coalesce formats
o Realign arguments
o Use %s, __func__ instead of embedded function names
o Remove unnecessary line continuations
