ASoC: ti: davinci-mcasp: Fix clk PDIR handling for i2s master mode

When running McASP as master capture alone will not record any audio unless
a parallel playback stream is running. As soon as the playback stops the
captured data is going to be silent again.

In McASP master mode we need to set the PDIR for the clock pins and fix
the mcasp_set_axr_pdir() to skip the bits in the PDIR registers above
AMUTE.

This went unnoticed as most of the boards uses McASP as slave and neither
of these issues are visible (audible) in those setups.
