[PATCH] pxa/mioa701: remove machine restart and halt code

[robert.jarzmik@free.fr (Robert Jarzmik)]

Remove all machine stop function which freed irq and gpio,
as this code is not necessary as the reboot are terminal
events, and won't suffer from a missing free.

Use the newly available machine descriptor soft_reboot field
to kill arm_pm_* hooks. This still ensures RTC clock is not
reset upon reboot.
