msm: kgsl: set userspace memory type on each memdesc
Userspace passes a set of values indicating how it
uses each buffer it allocates, which were previously
ignored. These are useful hints for debugging and
profiling applications. These flags will be exposed
through ftrace and debugfs in later patches.
