Simon Glass f783aee46f daisy: Refactor the power task ...

Add a set of functions to deal with power on/power off, and checking
the power button. Then use these functions in a new top-level power
control loop.

This implements the following features:

- Cold reset powers off the AP

When powered off:
- Press pwron turns on the AP
- Hold pwron turns on the AP, and then 16s later turns it off and leaves
it off until pwron is released and pressed again

When powered on:
- The PMIC PWRON signal is released one second after the power button is
released (we expect that U-Boot as asserted XPSHOLD by then)
- Holding pwron for 8s powers off the AP
- Pressing and releasing pwron within that 8s is ignored
- If XPSHOLD is dropped by the AP, then we power the AP off

BUG=chrome-os-partner:9424
TEST=very ad-hoc:
1. build and boot on daisy, flash U-Boot with USB using
'cros_bundle_firmware -w usb', inserting daisy
USB cable when it says 'Reseting board via servo...'
2. Press cold reset, then power on, see that it powers on
3. Then hold power-on for 8 seconds and see that it power off
4. XPSHOLD function not tested yet (this should work in Daisy 2)
