[0/3] iio: max31856: provide more configuration options

Message

This patch series makes it possible to configure some HW features at
runtime by introducing new IIO device attributes.

Two hardware features (power mains noise rejection and HW averaging)
were not previously configurable, and one (thermocouple type selection)
was only possible via DT, but in my experience this is quite limiting in
several scenario (see 3/3 commit message for complete explanation).

These patches have been tested backporting the driver on a 4.9 upstream
kernel (Xilinx mpsoc-based board), and then rebased on the IIO testing git
tree.

Andrea Merello (3):
  iio: max31856: add option for setting mains filter rejection frequency
  iio: max31856: add support for configuring the HW averaging
  iio: max31856: add support for runtime-configuring the thermocouple
    type
