CONFIG_ macros should be set directly. Expanding the task names in the same
way made it difficult to tell what was a configuration choice and what was
due to changes in ec.tasklist

And remove the daisy power button LED task for now. Since daisy
didn't have a board.c implementation (or a power button LED), its
power LED task did nothing.

The power LED now has its own tick-based handler which knows how to
blink the LED and resend the desired LED state to work around the
flaky 1-wire connection.
Removes a bunch of LED state code from charge_state.c.
No user-visible impact. Does not need to go into link branch.

1) Discharge battery to <97%
2) Plug in AC. LED=yellow
3) 'ectool chargeforceidle 1' from root shell. LED=blinking green/off.
4) 'ectool chargeforceidle 0' from root shell. LED=yellow.
5) Wait for battery >= 97% (or 'battfake 98' from EC console). LED=green.
6) Unplug battery. LED=red (may take 10 sec).
7) Replug battery. LED=green.

The spring board doesn't have one and we doesn't want to mess up with
that pin.
When the POWERLED task is not present, let's de-activate cleanly that
code.

Usually the power LED is driven by the PWM mode so that its nominal
brightness can be set to a "soft" on value. However, when
the LED is to remain off the LED should be switched to floating
input mode. This reduces voltage leakage.
This CL updates the power_led_task to configure the LED however is
appropriate and adds board functions to re-configure the GPIO.

This drives the power LED for Snow (PB3) using TIM2 in PWM mode.
Since timer setup and manipulation is STM32-specific, the power LED
logic moved to to chip/stm32/power_led.c.
This also adds a "powerled" console command for testing.
