Gustavo A. R. Silva 8baee57218 watchdog: pc87413: Mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/watchdog/pc87413_wdt.c: In function ‘pc87413_ioctl’:
drivers/watchdog/pc87413_wdt.c:439:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
   pc87413_refresh();
   ^~~~~~~~~~~~~~~~~
drivers/watchdog/pc87413_wdt.c:441:2: note: here
  case WDIOC_GETTIMEOUT:
  ^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
