ASoC: davinci-mcasp: correct tdm_slots limit

Browse Source 
The current check for the number of tdm-slots specified by platform data is
always true (x >= 2 || x <= 32); therefore the else branch that warns of an
incorrect number of slots can never be taken.

Check that the number of tdm slots specified by platform data is between 2
and 32, inclusive.
