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. This change is already incorporated for timer nodes in the MCU voltage domain.

checked only on J7200, for Main MCU 1-0, Looks you need main_timer2 as well to get it working
Please verify on other SOCs as well for all firmwares, if some extra nodes needs to be added
