Second round of IIO fixes for the 3.18 cycle.

* tsl4531 - fix a compile error when CONFIG_PM_OPS not set.
* kxcjk-1013 - event spec direction was invalid - leading to 'interesting'
  attrribute names.
* as3935 - sizeof(st) used instead of sizeof(*st) leading to allocation of
  space for a pointer rather than the structure desired.
* ade7758 - Another null pointer deref fix due to different channels
  being provided to the the buffer register than used for the sysfs
  side of things.
* ade7758 - Check there is a channel enabled in preenable for the buffer
  before doing anything.
* ade7758 - Drop a stray raw from the channel name that leads to _raw_raw
  postfix.
