For devices such as BTHOMEHUBV5A with both reset and restart buttons,
its easily accessible restart button has been assigned to KEY_POWER
power script to poweroff preventing accidental (or malicious) factory
resets by KEY_RESTART reset script. However an easily accessible button
immediately powering off the device is also undesirable.

As KEY_RESTART is already used for reset script (and there's no
KEY_REBOOT in Linux input events), use KEY_POWER2 for rebooting via new
reboot script with 5 second seen delay.

The build system already defines KERNEL_CROSS which defaults to TARGET_CROSS.
Make use of this variable for kernel makefiles.

The wimax key will be used as a generic wwan key starting with Linux
3.13. The brcm47xx target uses this key for the 3g buttons. Also remove
the ifdef around KEY_WPS_BUTTON, this is in the kernel for a long time
now.

When running OpenWrt within KVM KEY_POWER is generated from the ACPI
button driver when restarting or powering down the VM.

Extend button-hotplug to allow user space handlers for these events.
