usb: ulpi: Call of_node_put correctly

stable inclusion
from stable-v5.10.101
commit 2a17bd9f52104fc5c023499cf4c9bea3f10f2b1c
bugzilla: https://gitee.com/openeuler/kernel/issues/I5669Z

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=2a17bd9f52104fc5c023499cf4c9bea3f10f2b1c



--------------------------------

commit 0a907ee9 upstream.

of_node_put should always be called on device nodes gotten from
of_get_*. Additionally, it should only be called after there are no
remaining users. To address the first issue, call of_node_put if later
steps in ulpi_register fail. To address the latter, call put_device if
device_register fails, which will call ulpi_dev_release if necessary.
