Move the programming of the mode setting from init() to
buffer_postenable()
Split out a separate function to
only update the power/shutdown bit
This changes permits to more easily implement different
modes of measurements in further patches

Table 4 of the datasheet specifies the mode control, these are not
individual bits; add multi LED mode
Add multi-LED mode and fix MODE_MASK (3 bits wide, not 2)

The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure
elements will shortly go away.

Initialize the parent of the IIO device to the device that registered it.
This makes sure that the IIO device appears the right level in the device
hierarchy.

MAX30102 is an heart rate and pulse oximeter sensor that works using
two LEDS of different wavelengths, and detecting the light reflected
back.
This patchset adds support for both IR and RED LED channels which can
be processed in userspace to determine heart rate and blood oxygen
levels. The MAX30102 part isn't completely register and functional
compatible with the existing MAX30100 driver.
