Subject: [PATCH] uio: pruss: Deprecate use of this driver

This UIO driver was used to control the PRU processors found on various
TI SoCs. It was created before the Remoteproc framework, but now with
that we have a standard way to program and manage the PRU processors.
The proper PRU Remoteproc driver should be used instead of this driver.
Mark this driver deprecated.

The userspace tools to use this are no longer available, so also remove
those dead links from the Kconfig description.
