i2c: imx: support DMA defer probing
Return -EPROBE_DEFER when dma_request_slave_channel() because DMA driver
have not ready yet.
Move i2c_imx_dma_request() before registering I2C adapter to avoid
infinite loop of .probe() calls to the same driver, see "e8c220fac415
Revert "i2c: imx: improve the error handling in i2c_imx_dma_request()""
and "Documentation/driver-api/driver-model/driver.rst".
Use CPU mode to avoid stuck registering i2c adapter when DMA resources
are unavailable.
