watchdog: Don't select CONFIG_WATCHDOG and CONFIG_HW_WATCHDOG at the same time

Browse source 
Commit 06985289d4 ("watchdog: Implement generic watchdog_reset()
version") introduced an automatic selection of CONFIG_WATCHDOG by
CONFIG_WDT. But for boards selecting CONFIG_HW_WATCHDOG, like
boards have a powerpc 8xx, CONFIG_WATCHDOG shall not be selected
as they are mutually exclusive.

Make CONFIG_WATCHDOG dependent on !CONFIG_HW_WATCHDOG
