First commit fixes compilation under 64-bit and second actually enables
it.

  dmaengine: st_fdma: change dreg_line to long
  dmaengine: st_fdma: add COMPILE_TEST support

[PATCH dmaengine 1/2] dmaengine: st_fdma: change dreg_line to long

[Rosen Penev]

The code is encoding a pointer into an int which works fine with a
32-bit build. Not with a 64-bit one.
