ASoC: cs4349: Fix setting digital interface format
Mode Control - Register 02h
Digital Interface Format (DIF[2:0]) Bits 6-4
DIF2 DIF1 DIF0 Description
0 0 0 Left-Justified, up to 24-bit data
0 0 1 I²S, up to 24-bit data
0 1 0 Right-Justified, 16-bit data
0 1 1 Right-Justified, 24-bit data
1 0 0 TDM slot 0
1 0 1 TDM slot 1
1 1 0 TDM slot 2
1 1 1 TDM slot 3
The DIF_MASK is 0x70, so current code does not correctly set the DIFx
setting. Fix it.
