The goal of this series is to update the qcom-geni-serial driver to use
the DMA mode of the QUPv3 serial engine. This is accomplished by the last
patch in the series. The previous ones contain either various tweaks,
reworks and refactoring or prepare the driver for adding DMA support.

More work will follow on the serial engine in order to reduce code
redundancy among its users and add support for SE DMA to the qcom GENI
SPI driver.
