[PATCH 2/5] dma/dpaa2: remove DMA device in bus device

[David Marchand <david.marchand@redhat.com>]

A driver .dev_close op is automatically called when releasing a dma
device.
Move device specific unitialisation in this driver .dev_close op.

This leaves no user of the dmadev field in the fslmc device object.
