Title:
  [Feature] DMA: DW: Need add a private probe/remove for compound
  devices.

Status in intel:
  Fix Released
Status in linux package in Ubuntu:
  Fix Released

Bug description:
  For compound devices(dma engine built in a parent device, like ADSP), maybe we need add a private probe/remove function, with passing correct dev and mask.
  compound devices has a primary function with additional private DMA IP. The ID is unique for primary function, but there is no ID for DMA part. Thus, the primary ->probe has to get proper PCI BAR or ACPI resources and enumerate DMA device. That's why it requires to have some generic probe/remove which is not dependent to internal things of dw driver.

  Upstream status:
  Done in kernel 3.18-rc1
