Basically, this patch does the following:
1. Move the codes of parsing boot parameters from setup-common.c
to driver. In this way, code reader can know directly that
there are boot parameters that can change the timeout.
2. Make boot parameter 'booke_wdt_period' effective.
currently, when driver is loaded, default timeout is always
being used in stead of booke_wdt_period.
3. Wrap up the watchdog timeout in device struct and clean up
unnecessary codes.
