arm64: dts: ti: k3-j722s-main: Change timer nodes status to reserved

commit 05b27e27be88eb1b846418f5abf15948e8f59c35 from
git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git



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  |
	+===================+=============+
	| mcu_r5fss0_core0  | mcu_timer0  |
	+-------------------+-------------+
	| main_r5fss0_core0 | main_timer0 |
	+-------------------+-------------+
	| c7x_0             | main_timer1 |
	+-------------------+-------------+
	| c7x_1             | main_timer2 |
	+-------------------+-------------+

This change is already incorporated for timer nodes in the MCU voltage
domain with commit 3308a31c ("arm64: dts: ti: k3-am62: Add general
purpose timers for am62").
