dmaengine: dw: platform: Switch to acpi_dma_controller_register()

[ Upstream commit e7b8514e4d68bec21fc6385fa0a66797ddc34ac9 ]

There is a possibility to have registered ACPI DMA controller
while it has been gone already.

To avoid the potential crash, move to non-managed
acpi_dma_controller_register().

Fixes: 42c91ee71d6d ("dw_dmac: add ACPI support")
