soc/amd/picasso: initialize ACP device at init() time
The ACP device sits behind a bridge. Despite the logs indicating
the bridge is likely hooked up, there's some unusual behavior of
writes not sticking. Aside from the speculation of what's causing
the issues the initialization of the device should occur at init()
because of these potential dependencies.
