[PATCH 2/4] powerpc: Add ppc_progress() wrapper

[Michael Ellerman <michael@ellerman.id.au>]

There's quite a lot of code that does:

if (ppc_md.progress)
	ppc_md.progress(...)

So move that idiom into a wrapper. Having a wrapper also allows us
to have a fallback to printk if no progress routine is specified.
