i2c: mxs: suppress probe-deferral error message

Browse source 
[ Upstream commit 78a4471fa1a76a8bef4919105de67660a89a1e9b ]

During boot of I2SE Duckbill the kernel log contains a
confusing error:

  Failed to request dma

This is caused by i2c-mxs tries to request a not yet available DMA
channel (-EPROBE_DEFER). So suppress this message by using
dev_err_probe().
