watchdog: cmsdk: Convert to use DT generated label for device name

Browse source 
Convert driver to use DT_INST_0_ARM_CMSDK_WATCHDOG_LABEL instead of
CONFIG_WDT_0_NAME.  This requires we introduce a "label" property in all
the related dts files.  Also introduce a standard watchdog alias
('watchdog0') that can be utilized by sample/test code in the future.
