ASoC: rockchip: i2s-tdm: fix shift config for SND_SOC_DAIFMT_DSP_[AB]

BugLink: https://bugs.launchpad.net/bugs/2106494

[ Upstream commit 6b24e67 ]

Commit 2f45a4e ("ASoC: rockchip: i2s_tdm: Fixup config for
SND_SOC_DAIFMT_DSP_A/B") applied a partial change to fix the
configuration for DSP A and DSP B formats.

The shift control also needs updating to set the correct offset for
frame data compared to LRCK.  Set the correct values.
