serial: 8250_dma: power off device after TX is done

When any 8250 based driver sets up DMA and has UART_CAP_RPM capability enabled
the device is left powered on after transfer is done. We need to schedule a
device suspend operation when DMA completes the transfer.

The patch is based on the work done by the reporter.

dma-buf/sync_file: hold reference to fence when creating sync_file

Also good to sync in general since git tends to get confused with the
cherry-picking going on.

It also includes some drivers/dma/ changes, as those were needed by

Also in here is the long-suffering ACPI SPCR patchset, which was
passed around from maintainer to maintainer like a hot-potato. Seems I

various subsystem maintainers as well.
