Instead of passing around struct plafform_device, use struct device and save one level of dereferencing. This affects the following functions: * cppi41_add_chans * purge_descs * deinit_cpii41 * init_descs * init_cppi41 * cppi_glue_infos It's just a cosmetic cleanup that makes the code more readable.

With enabled pm_runtime in the kernel the device won't work because it is not "on" during the probe function. This patch enables the device via pm_runtime on probe so it remains activated.

This driver is currently used by musb' cppi41 couter part. I may merge both dma engine user of musb at some point but not just yet. The driver seems to work in RX/TX mode in host mode, tested on mass storage. I increaed the size of the TX / RX transfers and waited for the core code to cancel a transfers and it seems to recover. v2..3: - use mall transfers on RX side and check data toggle. - use rndis mode on tx side so we haveon interrupt for 4096 transfers. - remove custom "transferred" hack and use dmaengine_tx_status() to compute the total amount of data that has been transferred. - cancel transfers and reclaim descriptors v1..v2: - RX path added - dma mode 0 & 1 is working - device tree nodes re-created.
