If something fails in ci_hdrc_add_device() due to probe defer, we
shouldn't print an error message. Be silent in this case as we'll
try probe again later.

e gadget is never
started. Furthermore, we see timeout messages like:
timeout waiting for 800 in OTGSC
Let's workaround this by skiping the wait for BSV when we're
using an extcon for the vbus notification and let's properly
emulate the BSVIS event that would happen wh
o and disable the
power domain to match the 'inactive' state of the device. Let's
mark the device as active so that runtime PM doesn't improperly
power down this device when it's actually active.

The ULPI bus can be built as a module, and it will soon be
calling these functions when it supports probing devices from DT.
Export them so they can be used by the ULPI module.
