nb/amd/agesa/family14: Improve HTC threshold handling
According to BKDGs HTC temperature limit field indicates the threshold
where HTC becomes active. HTC active state means that processor is
limiting its power consumption and maximum P-State. Using this threshold
as _CRT is incorrect, since HTC active is designed to prevent
overheating, not causing immediate shutdown.
Change the behavior of temperature limit to act as a passive cooling
threshold. Make the passive cooling threshold a reference value for
critical and hot temperature with 5 degrees step.
TEST=boot FreeBSD on PC Engines apu2 and check the thermal zone
temperature using sysctl
