iio: sx9360: fix iio event generation 

To convert SX9360 status register ["REG_STAT"], into a channel
index, we need to right shift by |stat_offset|, not left shift.
Also the PROXSTAT bit (3) is for channel 1 (PHM, Phase Measured), not (PHR,
Phase Reference, channel 0), so the offset is 2 instead of 3.
