ArmPkg/GenericWatchdogDxe: Split 64bit register write to 2x32bit According to the SBSA specification the Watchdog Compare Register is split into two separate 32bit registers. EDK2 code uses a single 64bit transaction to update them, which can be problematic, depending on the SoC implementation and could result in unpredictable behavior. Fix this by modifying WatchdogWriteCompareRegister routine to use two consecutive 32bit writes to the Watchdog Compare Register Low and High, using new dedicated macros.
