hwmon: (gsc-hwmon) fix fan pwm setpoint show functions

commit 9c62e228 upstream.

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 a6d80df4 ("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
