drm/amdkfd: Add PM4 target XCC

Browse source

In a device that supports multiple XCCs, unlike AQL queues, the PM4 queue
will be only processed in one XCC in the partitioning. This patch
re-purposes the queue percentage variable in create queue and update
queue ioctl for the user space to specify the target XCC.
