[meta-ti] [PATCH] linux-ti33x-psp 3.1: add dto patch to fix problems with various sd cards

[Maupin, Chase]

Philip,

We use the dto=14 setting in the AMSDK from TI because this calculation only seems to work 50% of the time.  So I would be find with ditching the calculation altogether.

Sincerely,
