Without CONFIG_OF, we get a build failure in the reboot-mode
implementation:

drivers/power/reset/reboot-mode.c: In function 'reboot_mode_register':
drivers/power/reset/reboot-mode.c:72:2: error: implicit declaration of function 'for_each_property_of_node'; did you mean 'for_each_child_of_node'? [-Werror=implicit-function-declaration]
  for_each_property_of_node(np, prop) {

Add a Kconfig dependency like we have for the other users of
CONFIG_REBOOT_MODE.

Wouldn't this be more appropriate to add the "depends on OF" to "config 
REBOOT_MODE" section, since this is an error to `reboot-mode.c` unit?

It's too late for 5.3-stable now, as that would break existing configurations
that won't select REBOOT_MODE themselves, and it adds a bit of complexity,
but we could to it for 5.4 if you think that is necessary.
