During glink_tx(), G-Link can wait for an unlimited amount of time for
the remote side to queue an RX intent. In some cases, e.g. SSR, the wait
must be restricted to a short time, but in the current implementation,
glink_tx() can continue to block indefinitely.
Add a configurable timeout value to the G-Link channel context, which is
set in the channel open configuration. If the value is set to 0, treat
it as an infinite timeout. This allows a timeout to be put in place by
the client for sensitive cases such as SSR where a very limited amount of
time can be spent waiting for an intent.

This driver supports communication with secure processor subsystem
over glink transport layer.
The communication is based on using shared memory and interrupts.
This driver exposes interface to both kernel and user space.

In certain cases during a kernel panic,the interrupts on non-panicking
CPUs are disabled. Since CPU context cannot be collected by sending IPI
to those CPUs, we're limited to debug the problem. Forcing a watchdog

Hence adding support for the same.
