This function name conflicts with our desire to #define free() to
something else on sandbox. Since it deals with resources, rename it to
rfree().Signed-off-by: Simon Glass

Sometimes, there would be a need to exchange data between DMA provider
and DMA client which are very specific to DMA driver of the SoC/platform
and are not generic enough to be put into struct dma. Therefore, introduce
dma_get_cfg() interface to get DMA provider specific data from client
device. Clients can use unique configuration ID flags to get different
configuration data from DMA driver.Signed-off-by: Vignesh Raghavendra
