Cycles: Use more friendly GPU device name for AMD cards

For example, for RX480 you'll no longer see "Ellesmere" but will see
"AMD Radeon RX 480 Graphics" which makes more sense and allows to easily
distinguish which exact card it is when having multiple different cards
of Ellesmere codenames (i.e. RX480 and WX7100) in the same machine.
