[PATCH 2/2] hwmon/mc13783-adc: don't access struct mc13783 directly

[Uwe Kleine-KÃnig]

There is a shiny new mc13783 API function that can be used instead.

While at it refactor the code a bit to reduce code duplication a bit.

This removes the last user of <linux/mfd/mc13783-private.h> and so this
include file can go away.
