In any case it seems to me a board specific redefinition of the WATCHDOG_RESET macro would be less intrusive and risky than changing code that has been there since the beginning of time (well, at least more than 18 years).
The point is, we're being told that everything is moving to DM and better convert your board or else..., and nowadays CONFIG_WDT comes with it's own watchdog_reset() which is a rather more complicated beast than the board-specific ones that used to be sprinkled throughout (and out-of) the tree. So yes, for the past 18 years, nothing bad has probably come from doing a WATCHDOG_RESET even deep down in the guts of arch-specific primitives.
CONFIG_WDT comes with a watchdog_reset() when you defined CONFIG_WATCHDOG.
For boards like powerpc boards with embedded SOC watchdog that needs to be pinged from the very begining, we have CONFIG_HW_WATCHDOG and that's compatible with DM. See https://gitlab.denx.de/u-boot/u-boot/-/commit/a68256074f4239008c6d5c936bc0f8...
