dmaengine: acpi: Add kernel doc parameter descriptions

Kernel documentation script is not happy about absence of function parameter
descriptions:

drivers/dma/acpi-dma.c:163: warning: Function parameter or member 'data' not described in 'acpi_dma_controller_register'
drivers/dma/acpi-dma.c:247: warning: Function parameter or member 'data' not described in 'devm_acpi_dma_controller_register'
drivers/dma/acpi-dma.c:274: warning: Function parameter or member 'dev' not described in 'devm_acpi_dma_controller_free'

Append the descriptions of above mentioned function parameters.
