ASoC: dt-bindings: davinci-mcasp: Fix interrupt properties

Combinations of "tx" alone, "rx" alone and "tx", "rx" together are
supposedly valid (see link below), which is not the case today as "rx"
alone is not accepted by the current binding.

Let's rework the two interrupt properties to expose all correct
possibilities.
