msm: kgsl: add IOCTL_KGSL_GPUMEM_ALLOC_ID
Previously, the gpu address has been used to uniquely
identify each memory allocation. Upcoming patches will
introduce cases where an allocation does not always
have a gpu address, so an additional id is needed.
IOCTL_KGSL_GPUMEM_ALLOC_ID allocates pages and returns
an id.
IOCTL_KGSL_GPUMEM_FREE_ID frees an id. KGSL_SHAREDMEM_FREE
can still be used to free by GPU address, if it exists.
The id can also be passed to mmap(), shifted left by
PAGE_SIZE to get a CPU mapping for the buffer.
IOCTL_KGSL_GPUMEM_ALLOC_GET_INFO can be called to retrieve
the id and other information about the buffer.
