Subject: [PATCH] kernel/watchdog: add missing prototypes for weak functions

In commit 73ce0511c436 ("kernel/watchdog.c: move hardlockup detector to
separate file") two new functions were added ‘watchdog_nmi_enable’ and
‘watchdog_nmi_disable’ the functions were changed from static to weak.
In which case expose the function declarations in header file.

Silence the following gcc warnings:

  kernel/watchdog.c:109:12: warning: no previous prototype for ‘watchdog_nmi_enable’ [-Wmissing-prototypes]
  kernel/watchdog.c:115:13: warning: no previous prototype for ‘watchdog_nmi_disable’ [-Wmissing-prototypes]
