Memory controller drivers for v6.8, part two

Convert all drivers platform remove callback to the "remove_new" which
returns void.  Usual rationale from Uwe:

  The .remove() callback for a platform driver returns an int which
  makes many driver authors wrongly assume it's possible to do error
  handling by returning an error code. However the value returned is
  ignored (apart from emitting a warning) and this typically results in
  resource leaks.
