stepper: Introduce and use gpio_out_toggle_noirq()
The gpio_out_toggle() function in the sam3x8e and stm32f1 code was
only valid if it was called with irqs disabled.
Commits 018c5daa and 9c52ad43 enabled the lcd code which called
gpio_out_toggle() with irqs enabled. This could cause corruption of
the gpio state.
Introduce a gpio_out_toggle_noirq() function that will only be invoked
with irqs disabled, and fix gpio_out_toggle() on sam3x8e and stm32f1
so that it safe to call even if irqs are enabled.
