Transmit data pins will output zero when slots are masked or channels
are disabled. In CHMOD TDM mode, transmit data pins are tri-stated when
slots are masked or channels are disabled. When data pins are tri-stated,
there is noise on some channels when FS clock value is high and data is
read while

This patch seems to do this unconditionally. This is fine for
configurations where the SoC is the only thing
Looks good to me!

CHMOD, configures if transmit data pins are configured for TDM mode
or Output mode.
* (0) TDM mode, transmit data pins are tri-stated when slots are
masked or channels are disabled.
* (1) Output mode, transmit data pins are never tri-stated and
