[0/7] Introduce max12xx ADC support

Message

Hello, here is a patchset updating the existing max1027.c driver (for
10-bit max1027/29/31 ADCs) with a few corrections/improvements and
then introducing their 12-bit cousins named max1227/29/31.

As on my hardware setup the "start conversion" and "end of conversion"
pin are not wired (which is absolutely fine for this chip), I also
updated the driver and the bindings to support optional interrupts. In
this case, triggered buffers are not available and the user must poll
the value from sysfs.

Thanks,
Miquèl
