[ Upstream commit 964946b88887089f447a9b6a28c39ee97dc76360 ]
The ending NULL is not taken into account by strncat(), so switch to
snprintf() to correctly build 'debug_name'.
Using snprintf() also makes the code more readable.

[ Upstream commit 7b7a224b1ba1703583b25a3641ad9798f34d832a ]
The TI-SCI message protocol provides a way to communicate between
various compute processors with a central system controller entity. It
provides the fundamental device management capability and clock control
in the SOCs that it's used in.
The remove function failed to do all the necessary cleanup if
there are registered users. Some things are freed however which
likely results in an oops later on.
Ensure that the driver isn't unbound by suppressing its bind and unbind
sysfs attributes. As the driver is built-in there is no way to remove
device once bound.
We can also remove the ti_sci_remove call along with the
ti_sci_debugfs_destroy as there are no callers for it any longer.
