Subject: [PATCH v2 3/4] staging: vchiq: Simplify platform devices registration

The child platform devices registered by the vchiq driver currently
populates a struct platform_device_info with a name and parent device
and uses platform_device_register_full() to its registration.

It can be simplified by using platform_device_register_data() directly
(which encapsulates populating the platform_device_info struct and a
platform_device_register_full() call in itself).
