[PATCH v2 0/3] mfd: rn5t618: add ADC support

This series adds support for the ADC in the RN5T618/RC5T619.
It depends on the IRQ support added in the RTC support series here:
https://lore.kernel.org/lkml/20191220122416.31881-1-andreas@kemnade.info/

I tested the driver only with the RC5T619 but it should work with the with
the RN5T618 as well based on these facts:
- The corresponding register definitions originally went into the kernel
for the RN5T618
- Public datasheet sections about the ADC look same.
- Out-of-tree code for these chips look same regarding to ADC

But due to missing hardware I cannot test the patches 2/3 and 3/3 which
add support for the RN5T618 ADC.
I marked these untested patches as RFC, and IMHO they require a Tested-By.
Feel free to ignore them if the whole series would be delayed just because
of missing Tested-By for those.

Changes in v2:
- got an "Applied, thanks" message for the first two, so I do not include
them anymore
- some cleanups for the ADC driver itself
