i2c: imx: release DMA channels on probe error
i2c_imx_dma_request() acquires exclusive tx/rx DMA channels and is
optional: on errors other than -EPROBE_DEFER the driver falls back to
PIO mode and probe continues. If i2c_add_numbered_adapter() then fails,
probe returns through clk_notifier_unregister without releasing the
channels, because the remove callback is not invoked after a failed
probe.
Release the channels on the probe error path, mirroring
i2c_imx_remove().
