When powering Intel Edison module with 3.3V, the "reboot" command makes
the module stuck.
If the module is powered at a greater voltage, like 4.4V (as the Edison
Mini Breakout board does), reboot works OK.
This patch copies the behaviour from the official Intel Edison BSP,
where "IPCMSG_COLD_RESET" message was sent to SCU by default at
reboot time.
In the official BSP, sending the "IPCMSG_COLD_BOOT" message instead of
"IPCMSG_COLD_RESET" was possible, by using a kernel command
line parameter.

Hi,
I submitted again the patch, after taking into consideration Andy's suggestions.
Regards!
