GENMASK(6, 3) in CTRL_REG1 and GENMASK(6, 2) in CTRL_REG2 are marked
reserved. Do not changed the original value (not declared in the
datasheet) during power-down/suspend routines.
Fixes: e4a70e3e7d84 (iio: humidity: add support to hts221 rh/temp device)
Fixes: b7079eeac5da (iio: humidity: hts221: add power management support)
