[PATCH] drm/panthor: Fix kernel-doc in panthor_sched.c so it's visible

[PATCH] drm/panthor: Fix kernel-doc in panthor_sched.c so it's visible

[Steven Price]

Various substructures defined in panthor_sched.c have kernel-doc which
is silently ignored because it doesn't include the full path to the
member. Fix these issues so that the kernel-doc text is actually output
by including the name of the parent.

Fixes: de8548813824 ("drm/panthor: Add the scheduler logical block")
