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.
