zx_reboot_probe() increments refcnt of zx296702-pcu device node by
of_find_compatible_node() and leaves it undecremented on both
successful and error paths.

This change resolves a new compile-time warning
when built as a loadable module:
WARNING: modpost: missing MODULE_LICENSE() in drivers/power/reset/zx-reboot.o
see include/linux/module.h for more information
This adds the license as "GPL v2", which matches the header of the file.
MODULE_DESCRIPTION and MODULE_AUTHOR are also added.

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.
Export the module alias information using the MODULE_DEVICE_TABLE() macro.
Before this patch:
$ modinfo drivers/power/reset/zx-reboot.ko | grep alias
$
After this patch:
$ modinfo drivers/power/reset/zx-reboot.ko | grep alias
alias: of:N*T*Czte,sysctrlC*
alias: of:N*T*Czte,sysctrl

Including ARM related header file cause build failure
in i386 build because COMILE_TEST also involve building
zx driver. Remove the unnecessary include file.

Register with kernel restart handler instead of setting arm_pm_restart
directly.
