misc: fastrpc: Update dma_bits for CDSP support on Kaanapali SoC

DSP currently supports 32-bit IOVA (32-bit PA + 4-bit SID) for
both Q6 and user DMA (uDMA) access. This is being upgraded to
34-bit PA + 4-bit SID due to a hardware revision in CDSP for
Kaanapali SoC, which expands the DMA addressable range.
Update DMA bits configuration in the driver to support CDSP on
Kaanapali SoC. Set the default `dma_bits` to 32-bit and update
it to 34-bit based on CDSP and OF matching on the fastrpc node.
