ti-codecs-omapl138: Fix DMA resource allocation in DSP Server

   * This patch configures DMAN3 resources to be used by DSP
     * TCCs and PaRams configured to match those marked exclusively
       for DSP usage (and reserved accordingly in ARM linux kernel)
     * 12 TCC allocated
     * 50 PaRams
   * Scratch group sizing adjusted to match max 12 TCC available
