8f57f2310f power/reset: xgene: Register with kernel restart handler
Register with kernel restart handler instead of setting arm_pm_restart directly.

This patch also addresses the following compile warning.

drivers/power/reset/xgene-reboot.c: In function 'xgene_reboot_probe':
drivers/power/reset/xgene-reboot.c:77:17: warning:
	assignment from incompatible pointer type [enabled by default]

The warning was due to a mismatch between the type of arm_pm_restart
and the restart function.

745e19764a power/reset: xgene: Use mdelay instead of jiffies based timeout
jiffies are not running at this stage of system shutdown, meaning an
error in the reset function would never be reported. Replace with mdelay().

43160718d9 power/reset: xgene: Use local variable dev instead of pdev->dev
Using a local variable dev to point to the device is simpler then repeatedly
dereferencing pdev->dev.

ef288f9f65 power/reset: xgene: Return -ENOMEM if out of memory
It is customary to return an error code of -ENOMEM if the system
is out of memory. Also, in that case, the infrastructure will report
an error, so it is unnecessary to report it again.

d3ed534cca power/reset: xgene-reset: Fix prototype of xgene_restart()
The xgene-reset driver uses xgene_restart() as arm_pm_restart() but that
function should take an enum reset_type as the first argument rather than
a char. Fix this; the paramter is not referenced in the implementation.

67778e0eda power: Add APM X-Gene system reboot driver
Add APM X-Gene SoC system reboot driver. This driver handles only system
reboot. System shutdown is board specific and can be handled by board
driver or GPIO based shutdown driver.
