misc: don't use hwaddr as a type in trace events

Use types that are defined by QEMU in trace events caused build failures
for the UST trace backend:

  In file included from trace-ust-all.c:13:0:
  trace-ust-all.h:11844:206: error: unknown type name ‘hwaddr’

It only knows about C built-in types, and any types that are pulled in
from includs of qemu-common.h and lttng/tracepoint.h. This does not
include the 'hwaddr' type, so replace it with a uint64_t which is what
exec/hwaddr.h defines 'hwaddr' as. This fixes the build failure
