ion: add test device for unit tests to interact with dma_bufs
Add a /dev/ion-test device that will be created if CONFIG_ION_TEST
is set. The device accepts a dma_buf fd and allows reading and
writing to the backing memory using DMA-like apis or kernel mapping
apis. Can be used to test the dma_buf mapping ops, including
the ion implementations, from userspace.
