[PATCH 1/3] hwmon: (max31760) Fix the local temperature limit registers

[Stanislav Aleksandrov <lightofmysoul@gmail.com>]

temp2_max and temp2_crit use each other's registers, so reading them
shows the local limits swapped and writing temp2_max changes the
overtemperature (SHDN) threshold.

Use the high limit (0x0C) for temp2_max and the overtemperature limit
(0x08) for temp2_crit.

Fixes: 38b04ad02d0d ("drivers: hwmon: Add max31760 fan speed controller driver")
