The remoteproc firmware like of R5F and DSPs in the MAIN voltage domain
use timers. Therefore, change the status of the timer nodes to
"reserved" to avoid any clash. Usage is described as below:
+===================+=============+
| Remoteproc Node | Timer Node |
+===================+=============+
| main_r5fss0_core0 | main_timer0 |
+-------------------+-------------+
| c7x_0 | main_timer1 |
+-------------------+-------------+
| c7x_1 | main_timer2 |
+-------------------+-------------+

Since IPC is not up-streamed for J722S , So I suggest to drop this patch
from this series
and include this when you upstream IPC support for J722S board .
