Subject: [PATCH 2/2] staging: vchiq_arm: add prototype of function vchiq_platform_init()

Fix "no previous prototype" W=1 warning by adding the prototype of the
function vchiq_platform_init().

Note: vchiq_platform_init() is only called once in vchiq_probe(), so
presumably should be static function. However, making the function
static breaks the build.
