All the proposals were implemented, and 2 extra patches were added (Patch 2 and
patch 4) in order to have better logical split between patches.

Changes in v2:

Patch 1: Sorted and removed headers as per request.

Patch 2: *NEW* Patch, adds coefficients for IIO units in the chip_info
structure as per request, remove them from the read_* functions.

Patch 3: Patch 2 of v1. Added RAW values as well, as per request.

Patch 4: *NEW* Remove the temperature reading from inside read_* functions so
the addition of a buffer for userspace is facilitated + make the code much more
intuitive.

Patch 5: Patch 3 of v1. No logical change, only minor typos as per request.

Patch 6: Patch 4 of v1. Previous commits allowed for much cleaner approach as
per request. Dropped filling of extra buffer in the read_* functions.
Patch 4 allows to put extra buffer in the union of the chip_info and fill
the buffer in the buffer_handler function.
