mediatek: filogic: bpi-r3-mini: Fix pwm-fan config

This patch did multiple modifications on pwm-fan related config for
Banana Pi R3-Mini.
1. Remove suffix zero on pwm-fan's pwms. [1]
2. Add "map-" prefix for cooling-maps. [2]
3. Change cooling-levels for pwm-fan to make sure the fan would start
spining when using Sinovoip's official case.
4. Change cooling-device level config to follow common implementation.
