Revert "i2c: qcom-geni: Disable DMA processing on the Lenovo Yoga C630"

Browse Source 
A combination of recent bug fixes by Doug Anderson and the proper
definition of iommu streams means that this hack is no longer needed.
Let's clean up the code by reverting '127068abe85b ("i2c: qcom-geni:
Disable DMA processing on the Lenovo Yoga C630")'.
