hwmon: (gsc-hwmon) fix fan pwm setpoint show functions
The Linux hwmon sysfs API values for pwmX_auto_pointY_pwm represent an
integer value between 0 (0%) to 255 (100%) and the pwmX_auto_pointY_temp
represent millidegrees Celcius.
Commit a6d80df47ee2 ("hwmon: (gsc-hwmon) fix fan pwm temperature
scaling") properly addressed the incorrect scaling in the
pwm_auto_point_temp_store implementation but erroneously scaled
the pwm_auto_point_pwm_show (pwm value) instead of the
pwm_auto_point_temp_show (temp value) resulting in:
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_pwm
25500
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_temp
4500
Fix the scaling of these attributes:
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_pwm
255
# cat /sys/class/hwmon/hwmon0/pwm1_auto_point6_temp
45000
