[RFC 1/4] driver core: Register SoC bus after platform bus

[Thierry Reding <thierry.reding@gmail.com>]

Instead of registering the SoC bus as a core initcall, call it directly
from driver_init() to make it explicit when it is called. This is done
in preparation for early device registration support.
