[PATCH 1/2] ArmPlatformPkg: Add PCD for SBSA Watchdog Count

[evan.lloyd@arm.com]

From: Sami Mujawar <sami.mujawar@arm.com>

The Juno and FVP platform implement SBSA Watchdog timers.
Added PcdWatchdogCount to specify the number of Watchdog timers
that are available.

This allows configurability and an option to disable the Watchdog
timers if required for testing.
