dmaengine: shdma: Fix up fallout from runtime PM changes.
The runtime PM changes introduce sh_dmae_rst() wrapping via the
runtime_resume helper, depending on dev_get_drvdata() to fetch the
platform data needed for the DMAOR initialization default at a time
where drvdata hasn't yet been established by the probe path, resulting
in general probe misery:
