powerpc/83xx: Add shutdown request support to MCU handling on MPC8349 MITX
This patch add support for calling ctrl_alt_del() when the power button is
pressed for more than about 2 seconds on some freescale MPC83xx evaluation
boards and reference design.
The code uses a kthread to poll the CTRL_BTN bit each second.
Also change Kconfig entry of the driver to bool, as device's gpio
registration is broken when loading as module.
Tested on an MPC8315E RDB board.
