[WATCHDOG] mpc8xxx_wdt: fix modular build

Fix the following build error when mpc8xxx_wdt is selected to build as a
module:

drivers/watchdog/mpc8xxx_wdt.c:304: error: redefinition of '__inittest'
drivers/watchdog/mpc8xxx_wdt.c:298: error: previous definition of '__inittest' was here
drivers/watchdog/mpc8xxx_wdt.c:304: error: redefinition of 'init_module'
drivers/watchdog/mpc8xxx_wdt.c:298: error: previous definition of 'init_module' was here
