watchdog: s3c2410_wdt: Add support for WTCON register DBGACK_MASK bit

Browse source

The WDT uses the CPU core signal DBGACK to determine whether the SoC
is running in debug mode or not. If the DBGACK signal is asserted and
DBGACK_MASK bit is enabled, then WDT output and interrupt is masked
(disabled).

Presence of the DBGACK_MASK bit is determined by adding a new
QUIRK_HAS_DBGACK_BIT quirk. Also update to use BIT macro to avoid
checkpatch --strict warnings.
