Subject: [PATCH] ASoC: fsl_ssi: remove duplicated flag setting in
 fsl_ssi_setup_reg_vals()

We don't need to set CCSR_SSI_SIER_RFF0_EN / CCSR_SSI_SIER_TFE0_EN bits
in reg->rx.sier / reg->tx.sier variables in a non-AC'97 mode considering we
had just initialized these variables to these very values unconditionally a
few lines earlier.
