nvapi: zotac rgb led support, to improve..

Browse Source 
zotac cards doesnt allow a real RGB value, so i converted manually
the card seems to handle it, but seems to lock sometimes for some time...

colors can be tested with "ccminer -d 2 --led=0x1f1f00 -Dn"

but... unsure the card handle it fast enough to be fully usable
