To enable detection of qemu SBSA generic watchdog timer device,this
patch has been added to create sbsa-wdt entry into the GTDT table
which helps firmware report the presence of SBSA-wdt to the OS.
Changes in v4:
- fixed indentation

SBSA generic watchdog timer structure entry has been added
to GTDT table as per SBSAv6.0.
This enables acpi detection of wdt in qemu sbsa platform
