Additional follow-up the PR #3631(Encapsulate Stepper, Planner, Endstops in singleton classes) ・Change from abort_on_endstop_hit to stepper.abort_on_endstop_hit in endstop.cpp, Marlin_main.cpp, and ultralcd.cpp ・Add include path to cardreader.h and temperature.h in endstop.cpp(for CardReader class and disable_all_heaters()) It fix compilation error when ABORT_ON_ENDSTOP_HIT_FEATURE_ENABLED and SDSUPPORT are enabled. ・Change from digipot_current() to stepper.digipot_current() in Marlin_main.cpp ・Change from digitalPotWrite() to stepper.digitalPotWrite() in Marlin_main.cpp It fix compilation errors when HAS_DIGIPOTSS is enabled. ・Change from microstep_mode() to stepper.microstep_mode() in Marlin_main.cpp ・Change attribute of microstep_mode() from private to public in stepper.h ・Change from microstep_readings() to stepper.microstep_readings() in Marlin_main.cpp ・Change from microstep_ms() to stepper.microstep_ms() in Marlin_main. It fix compilation errors when HAS_MICROSTEPS is enabled.
