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

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().

Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202308211837.4VBSUAtZ-lkp@intel.com/
