powerpc: add fsl,fifo-depth property to Freescale SSI device nodes
The Freescale Serial Synchronous Interface (SSI) is an audio device present on some Freescale SOCs. Various implementations of the SSI have a different transmit and receive FIFO depth, but are otherwise identical. To support these variations, add a new property fsl,fifo-depth to the SSI node that specifies the depth of the FIFOs. Also update the MPC8610 HPCD device tree with this property.
