If a thread wants to block a state transition it can use
thread_run_until. Otherwise just let the thread run. `thread_join` can
be used to block on the thread. Boot states are also a ramstage concept.
If we want to use this API in any other stage, we need a way of starting
a thread without talking about stages.

The thread_handle can be used to wait for a thread to exit. I also added
a return value to the thread function that will be stored on the handle
after it completes. This makes it easy for the callers to check if the

method uses the handle to block until the thread completes.

The patch adds an interface for configuring GPIOs inside the Kontron
CPLD/EC. This allows to statically define the mode for each GPIO pin
in devicetree.cb of the motherboard or carrier board. For example:
chip ec/kontron/kempld
device gpio 0 on
register "gpio[0]" = "KEMPLD_GPIO_INPUT"
register "gpio[4]" = "KEMPLD_GPIO_OUTPUT_LOW"
register "gpio[5]" = "KEMPLD_GPIO_OUTPUT_HIGH"
register "gpio[11]" = "KEMPLD_GPIO_DEFAULT"
end
end
In this case, <device gpio 0>, like all other devices, is not a real
device inside the EC. These definitions are used to understand the EC
resources and systematize configuration options, but if mark this as
<off>, the initialization step will be skipped in the driver code.
Use KEMPLD_GPIO_DEFAULT or skip it in devicetree.cb to not configure
the GPIO and keep the default mode after CPLD reset.
This work is based on code from the drivers/gpio/gpio-kempld.c linux
driver. Tested on Kontron mAL-10 COMe module [1].
