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 v3:
- fixed typo from earlier patch which was resulting in build failure
- confirmed the overall functionality using latest build and
testing with related qemu code for sbsa wdt

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
