msm: kgsl: Add accounting for memory mapped in userspace
For proper memory accounting, a key metric is to know how much
memory kgsl allocated for a process and how much of it the process
is actually using. This is done by keeping track of memory in our
vmfault routines. This information is provided via the process
mem file.
