[PATCH v2] dmaengine: sirf: add PM entries for sleep and runtime

[Barry Song]

2013/7/30 Barry Song <21cnbao at gmail.com>:
> this patch adds PM ops entries in sirf-dma drivers, so that this
> driver can support suspend/resume, hibernation and runtime PM.
>
> while suspending, sirf-dma will lose all registers, so we save
> them at suspend and restore in resume for active channels.
