Pull regmap fix from Mark Brown:
 "Fix registers file in debugfs

  Ensure that the mode reported for the registers file in debugfs is
  accurate by marking it as read only when the define to enable writes
  has not been set.  This is on the edge of being a bug fix but it's
  debugfs and it makes it much easier for users to spot what's going
  wrong when they forget to enable writeability"
