apm821xx: WNDR4700: fix fan-control

This service was unfunctional due to not having its executable bit set.
Furthermore, sysupgrade complains about the file being present in images.

Also, the tc654 driver doesn't provide pwm1_enable sysfs file, instead its
now called pwm1_mode.

Please note that the fan was always spinning. It should now turn off, when
there's enough the thermal headroom.
