hwmon: (lm90) Add support for ON Semiconductor NCT214 and NCT72
NCT214 and NCT72 are compatible to ADT7461/ADT7461A but have full
PEC (packet error checking) support. PEC support is undocumented.
Both chips support the undocumented secondary chip and manufacturer
ID registers at 0x3e and 0x3f, and return 0x61 as chip ID. Use this
information to improve the accuracy of chip detection code.
