ArmPlatformPkg/PL031RealTimeClockLib: cast EfiTimeToEpoch() val. to UINT32
In preparation for changing EfiTimeToEpoch()'s return type to UINTN, cast EfiTimeToEpoch()'s retval to UINT32 explicitly, in LibSetTime(). Currently, this is a no-op, and even after widening the retval, it will make no difference, as LibSetTime() explicitly restricts Time->Year under 2106, given that "the PL031 is a 32-bit counter counting seconds". The patch is made for preventing compiler warnings.
