Follow-up the PR #3643(Temperature singleton) ・Change from fanSpeedSoftPwm[0] to thermalManager.fanSpeedSoftPwm[0] in planner.cpp It fix compilation error when FAN_SOFT_PWM is enabled. ・Remove declaration of setExtruderAutoFanState() in temperature.h Because that function was abolished. ・Change from babystepsTodo to thermalManager.babystepsTodo in ultralcd.cpp It fix compilation errors when BABYSTEPPING is enabled.
