ec: Use EC command to toggle power button if pwr_button not available
Usually, we use the power button line in the servo debug header to
control the state of power button. On CCD, this way is not feasible.
We switch to use EC command to toogle the power button. It is done
by setting the new control pwr_button_hold which accepts a hold
interval.
We remove the pwr_button control from Cr50 CCD config. Because on
some boards, it doesn't work. Safe to not use it.
