i2c: qcom-geni: make sure I2C hub controllers can't use SE DMA

Browse source

[ Upstream commit c0c50e3743 ]

The I2C Hub controller is a simpler GENI I2C variant that doesn't
support DMA at all, add a no_dma flag to make sure it nevers selects
the SE DMA mode with mappable 32bytes long transfers.
