3.18-stable review patch. If anyone has any objections, please let me know.

From: Bjorn Andersson <bjorn.andersson@xxxxxxxxxx>
commit d50daa2af2618dab6d21634e65a5fbcf4ae437d6 upstream.
Include the OF-based modalias in the uevent sent when registering SPMI
devices, so that user space has a chance to autoload the kernel module
for the device.
