Power off machine while waiting for CR50 update to take effect.

Whether to request longer interrupt pulses using Cr50 BOARD_CFG register.
If the Cr50 firmware is too old, it will not be able to honor the request.

help
Timeout in milliseconds for waiting for TPM IRQ. Default to 100ms/10ms on platforms
using Cr50 in order to support legacy pre-ready-IRQ cr50 factory images. Default to
750ms otherwise.
config CR50_RESET_CLEAR_EC_AP_IDLE_FLAG
def_bool n
help
Select this if the variant is a Chromebox/base. This allows AP to direct EC
to clear AP_IDLE flag after AP shutdown before triggering CR50 reset and
shutting down AP so that AP can boot up after CR50 reset.
