The remoteproc firmware like of R5F and DSPs in the MAIN voltage domain
use timers. At the same time, if Linux probes the timers, some
instability is observed while booting remote cores. Therefore, change
the status of the timer nodes to "reserved" to avoid any clash.
v3: Changelog:
* Udit
1) j7200: Updated commit message description to remove DSPs as the SoC does not
have one.
2) j722s: Updated the correct commit for "Fixes:" tag which introduced the bug.
3) For entire series, removed comment about timer usage by R5fs in the MCU
voltage domain as those are used by Device Manager firmware to get SoC
functional.

v2: Changelog:
- Split the changes into individual patches for each SoC to tag the
correct offending commit for "Fixes:" tag.
* Udit
1) Add the correct clashing timer nodes for J7200 SoC.
2) Port these changes to board level dts files instead of SoC level dtsi files.

All patches: please fix your $subject. it looked initially like
Thanks for pointing out, fixed this in v4 revision.
you were fixing the default SoC behavior, but later I realized
you are fixing the evm solution.
Also while at this make sure the corresponding SK behaviors are in sync
Thanks for catching this. I have included timer changes for SK boards in
the v4 revision.
correctly as well. if you think they do not need to be fixed, address
that comment in the cover-letter.
