This patch adds support for Lattice's POWR1014 power manager IC. Read
access to all the ADCs on the chip are supported through the hwmon
sysfs files.

The main difference of POWR1014 compared to POWR1220 is amount of VMON
input lines: 10 on POWR1014 and 12 lines on POWR1220.

Please use an is_visible function instead of duplicating the attribute
pointer arrays.

Thanks,
