  Use the wrapper functions for getting and setting the driver data using
  spi_device instead of using dev_{get|set}_drvdata with &spi->dev, so we
  can directly pass a struct spi_device.

  These are now removed from the kernel, so remove them to allow the
  driver to build properly.

  This patch adds support for bitstream configuration (programming /
  loading) of the Lattice ECP3 FPGA's via the SPI bus.

  Here an example on my custom MPC5200 based board:

  $ echo 1 > /sys/class/firmware/spi0.0/loading
  $ cat fpga_a4m2k.bit > /sys/class/firmware/spi0.0/data
  $ echo 0 > /sys/class/firmware/spi0.0/loading

  leads to these messages:

  lattice-ecp3 spi0.0: FPGA Lattice ECP3-35 detected
  lattice-ecp3 spi0.0: Configuring the FPGA...
  lattice-ecp3 spi0.0: FPGA succesfully configured!
