drm/amdgpu: Move KFD sched stop/start into PTL control path

Browse source

Move amdgpu_amdkfd_stop/start_sched calls from kfd_ptl_control()
into amdgpu_ptl_perf_monitor_ctrl() so all PTL callers (KFD ioctl,
sysfs, GFX init) get consistent scheduling management.

Add amdgpu_amdkfd_stop/start_sched_all() wrappers to stop and
restart KFD scheduling on all nodes without assuming node ID ordering.

v3:
 * call start/stop for PTL Set Only
v2:
 * move the stop/start sched function to
   amdgpu_ptl_perf_monitor_ctrl(Lijo)
 * add wrapper amdgpu_amdkfd_stop_sched_all and
   amdgpu_amdkfd_start_sched_all (Lijo)
