watchdog: at91rm9200: Remove #ifdef guards for PM related functions

Use the pm_ptr() macro to handle the .suspend/.resume callbacks.

This macro allows the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_SUSPEND is disabled, without having
to use #ifdef guards. Not using #ifdef guards means that the code is
always compiled independently of any Kconfig option, and thanks to that
bugs and regressions are easier to catch.

watchdog: db8500_wdt: Rename driver

This driver is named after the ambition to support more SoCs than
the DB8500. Those were never produced, so cut down the scope and
rename the driver accordingly. Since the Kconfig for the watchdog
defaults to y this will still be built by default.
