Note that this patch also makes 2 changes to the code paths for the f71889fg
to keep the code unified between the 2 (for simplicities sake). Both of these
are harmless for then f71889fg:
1) The first change is to always set the FAN_PROG_SEL bit to 0. This influences
accesses to some banked fan / pwm registers. On the f71889fg no registers
which we use are banked. On the f71889ed however some more fan registers
have been banked including one which we use, by making the FAN_PROG_SEL bit
0, address 0x96 will point to the right register.
2) The second change is to see a FANx_TEMP_SEL value of 0 as pointing to
a PECI / AMDSI value, and thus disable our pwm related sysfs attr.
This is correct for the f71889ed and on the f71889fg 0 is a reserved
value, so we should never see it and if we do, disabling the pwm related
sysfs attr is a sane thing to do.

if the fan divider is set to a low value, which results in a fan speed reading

PMBus only has one set of limit registers for up to three temperature sensors.
Thus, changing a limit for one of the temperature sensors affects limits for
other temperature sensors in the same page (and potentially multiple pages

temperature limit registers when updating sensor data. This way, all affected
temperature limits are updated whenever the limit for a single sensor is
