Hi all,

this is a long overdue v2 for fixes [1] related to adc-joystick channel
parsing.

Patch [1/2] now also addresses a case where a readout of ADC data
containing samples for two channels, where only one channel is active,
would push the data into a buffer without discarding the disabled
channel first.

Patch [2/2] addresses concerns about exposure to channels the clients
shouldn't know about. The IIO helpers from v1 are gone and the offsets
are now calculated based only on the channels adc-joystick has access
to.

Tested on GCW Zero (by me) and on Anbernic RG350 (by Paul).
