watchdog/mpc8xxx: add a const qualifier

Browse Source 
This prepares *of_device_id.data becoming const. Without this change
the following warning would occur:

	drivers/watchdog/mpc8xxx_wdt.c: In function 'mpc8xxx_wdt_probe':
	drivers/watchdog/mpc8xxx_wdt.c:203:11: warning: assignment discards 'const' qualifier from pointer target type [enabled by default]
