mfd: da9061: Fix Failed to set Two-Wire Bus Mode.

In da9062_i2c_probe() regmap_clear_bits() tries to access CONFIG_J
register. As CONFIG_J is not present in da9061_aa_writeable_ranges[] probe
of da9061 fails:

  da9062 2-0058: Entering I2C mode!
  da9062 2-0058: Failed to set Two-Wire Bus Mode.
  da9062: probe of 2-0058 failed with error -5

Add CONFIG_J register to da9061_aa_writeable_ranges[].
