Can not get memory read/write bandwidth on ARC A770 #83

In previous versions, such as 1.2.27, it can get memory read/write bandwidth through the GPUDeviceStub::toGetMemoryReadWrite member function. image

But in the latest release version, such as 1.2.36, it can not get memory read/write bandwidth on ARC A770. This is because the maxBandwidth value obtained from the driver is 0. image

So it better to decouple Read/Write bandwidth from total bandwidth utilization. Thanks.
