Fifth set of IIO fixes for the 4.11 cycle.

As these are rather late in the cycle, they may sneak over into 4.12.
There is a fix for a regression caused by another fix (hid sensors
hardware seems to vary a lot in how various corner cases are handled).

* ad7303
  - fix channel description. Numeric values were being passed as characters
  presumably leading to garbage from the userspace interface.
* as3935
  - the write data macro was wrong so fix it.
* bmp280
  - incorrect handling of negative values as being unsigned broke humidity
  calculation.
* hid-sensor
  - Restore the poll and hysteresis values after resume as some hardware
  doesn't do it.
* stm32-trigger
  - buglet in reading the sampling frequency
