Here's what I'm going to apply:

commit 913552b8c7a0f06cc1bff27f8e9953bffe6a1817

    rpmsg: fix dependency on initialization order

    When rpmsg drivers are built into the kernel, they must not initialize
    before the rpmsg bus does, otherwise they'd trigger a BUG() in
    drivers/base/driver.c line 169 (driver_register()).

    To fix that, and to stop depending on arbitrary linkage ordering of
    those built-in rpmsg driver, we let the rpmsg bus initialize at
    subsys_initcall.
