First set of IIO fixes for the 4.19 cycle.

* ad9523
   - sysfs write should return the number of characters used or an error, not
     0 which could result in an infinite loop in userspace.
 * lsm6dsx
   - Fix computation of length when updating the watermark to include
     timestamps avoiding the watermark being set earlier than intended.
 * maxim_thermocouple
   - Revert a patch adding the max31856 as it's not actually compatible with
     the register set that this driver supports.
 * si1133
   - Fix an impossible value check so we don't always error out whether the
     passed in value is good or bad.
