[PATCH v5 3/3] dmaengine: qcom: deprecate redundant of_device_id entries

[Richard Acayan <mailingradian@gmail.com>]

The drivers are transitioning from matching against lists of specific
compatible strings to matching against smaller lists of more generic
compatible strings. Add a message that the compatible strings with an
ee_offset of 0 are deprecated except for the SDM845 compatible string.
