[PATCH] tracing, powerpc: Add data parameter to powerpc-specific tracepoints

[Paul Mackerras <paulus@samba.org>]

Commit 38516ab5 ("tracing: Let tracepoints have data passed to
tracepoint callbacks") added a void *data parameter to tracing
callbacks and to the {un,}register_trace_* functions, requiring all
tracepoint callback functions to have the extra void * parameter.

This adds the void *data parameter to the tracepoints in the pSeries
hypervisor call code.  Without this, hvCall_inst.c fails to compile
with tracing enabled.
