spi_engine: Add NUM_OF_SDI value into register map 

The value of the HDL parameter NUM_OF_SDI can be read out from the
register at address 0x0C. The same register contains the value of the
DATA_WIDTH.
The register has the following bit layout:
  [15: 0]  DATA_WIDTH
  [23:16]  NUM_OF_SDI
  [31:24]  8'b0
