soundwire: cadence: add BTP/BRA helpers to format data
The Cadence IP expects a specific format (detailed in the
Documentation). Add helpers to copy the data into the DMA buffer.
The crc8 table is for now only used by the Cadence driver. This table
might be moved to a common module at a later point if needed by other
controller implementations.
