[PATCH] ARM: restart: davinci: use new restart hook

Mon Nov 14 13:52:55 EST 2011
Rather than using davinci specifci davinci_soc_info based
restart hook, use the existing arm_pm_restart pointer
instead.
This should finally graduate to using the restart
hook provided in machine descriptor, but that needs
more local header files in davinci.
Tested on DM365 and AM18x EVMs.
