This CL simplified TACH_TO_RPM formula and abstracted two definitions (PULSES_ROUND and RPM_DEVIATION) for the pwm-type fan used on boards. The developers can modify them in board-level driver if fan doesn't meet the default spec. In this CL, it also fixed: 1. Declare rpm_pre as array if FAN_CH_COUNT > 1. 2. Add checking for the value of next duty of pwm. 3. Use TAPND pending bit to make sure TCRA is valid. BRANCH=none BUG=none TEST=test fan used in kahlee and Sunon fan with fanset command on npcx_evb and use faninfo for verifying. Measure the actual rpm by scope.
