hwmon: (npcm-750-pwm-fan) Change initial pwm target to 255

Browse Source 
[ Upstream commit f21c8e753b1dcb8f9e5b096db1f7f4e6fdfa7258 ]

Change initial PWM target to 255 to prevent overheating, for example
when BMC hangs in userspace or when userspace fan control application is
not implemented yet.
