dmaengine: dw: balance PM runtime calls
In case of PCI driver we will get a warning:
dw_dmac_pci 0000:00:18.0: Unbalanced pm_runtime_enable!
dw_dmac_pci 0000:00:18.0: DesignWare DMA Controller, 8 channels
This happens due to pm_runtime_enable() call from the driver when PM runtime is
enabled by core.
This patch moves that call to the platform driver where it might make sense.
Fixes: bb32baf76e56 (dmaengine: dw: enable runtime PM)
