The remoteproc firmware of R5F 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, main_timer2 |
	+-------------------+--------------------------+
	| main_r5fss0_core1 | main_timer1              |
	+-------------------+--------------------------+
