Subject: [PATCH v2] [WATCHDOG] mpc8xxx_wdt: fix modular build

This patch fixes 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

Reported-by: Dave Jones <davej@...hat.com>
Signed-off-by: Anton Vorontsov <avorontsov@...mvista.com>

CONFIG_8xxx_WDT_MODULE -> MODULE, per Adrian Bunk's comment.
