[PATCH] watchdog: stm32: Drop unnecessary of_match_ptr()

[Rob Herring]

With COMPILE_TEST recently enabled, 0-day reports a warning:

drivers/watchdog/stm32_iwdg.c:215:34: warning: 'stm32_iwdg_of_match' defined but not used [-Wunused-const-variable=]

As STM32 platforms are always used with DT, drop the of_match_ptr().
