While we are executing do_idle() API, it is possible that
unrailgate() gets invoked in midst of idling the GPU and
this can result in failure of do_idle()
To prevent simultaneous execution of these methods,
add a mutex railgate_lock and acquire it during
do_idle() and unrailgate() APIs
Also, keep this lock held if do_idle() is successful.
In success, lock will be released in do_unidle(),
otherwise release this lock before returning
Note that this lock should not be held in railgate() API
since we do not want it to be blocked during do_idle()

Do not abort GPU probe if secure page alloc fails.
We can just note that this allocation failed (using bool
secure_alloc_ready) and prevent further secure memory
allocation if this flag is not set.
