Oak Zeng 41a9f7d480 Allocate coherent uncached memory when HSA_DISABLE_CACHE is set ...

Set the KFD_IOC_ALLOC_MEM_FLAGS_COHERENT flag  and
KFD_IOC_ALLOC_MEM_FLAGS_UNCACHED flag to allocate
uncached coherent memory when HSA_DISABLE_CACHE
environment variable is set. At KFD driver,
Single KFD_IOC_ALLOC_MEM_FLAGS_UNCACHED flag is
not sufficient to allocate uncached memory. We
have to use both two flags to allocate uncached
memory.
