Add support for 6 temperature limit registers on IT8628E

Browse Source 
IT8628E has 6 temperature limit registers, overlayed with VIN7..VIN9
limit registers, but only 3 temperature offset registers. Given that,
introduce separate variables for the number of temperature limit
registers and the number of temperature offset registers.
