drm/amd/pm: disable OD_FAN_CURVE if temp or pwm range invalid for smu v14
Forcibly disable the OD_FAN_CURVE feature when temperature or PWM range is invalid,
otherwise PMFW will reject this configuration on smu v14.0.2/14.0.3.
example:
$ sudo cat /sys/bus/pci/devices/<BDF>/gpu_od/fan_ctrl/fan_curve
OD_FAN_CURVE:
0: 0C 0%
1: 0C 0%
2: 0C 0%
3: 0C 0%
4: 0C 0%
OD_RANGE:
FAN_CURVE(hotspot temp): 0C 0C
FAN_CURVE(fan speed): 0% 0%
$ echo "0 50 40" | sudo tee fan_curve
kernel log:
[ 969.761627] amdgpu 0000:03:00.0: amdgpu: Fan curve temp setting(50) must be within [0, 0]!
[ 1010.897800] amdgpu 0000:03:00.0: amdgpu: Fan curve temp setting(50) must be within [0, 0]!
