The comment is misleading and incorrect, remove it.
Printing the id is completely meaningless and this practice
can cause a race conditions on command submission.
The flags and hangs fields are completely unused.
Give all fields a common indentation.
v2: remove fpriv reference and unused flags as well, fix debug message.

CGS (Common Graphics Services) is an AMD cross component
abstraction layer to designed to better encapsulate
specific IP block drivers so different teams can effectively
work on differnet IP block drivers independently. It provides
a common interface for things like accessing registers,
allocating GPU memory, and registering interrupt sources.
The plan is to eventually move more and more IP drivers to
this interface. The first user is the ACP IP driver.

Two small bug fixes for the code you pulled for 4.3:
- Used a SHIFT define instead of a MASK define to check if a bit is turned on
when destroying hqd. Luckily, this is in gfx7 interface file with amdgpu,
which was used only for bring-up purposes of amdgpu, so no real effect on
a running system
- Used a logical AND instead of a bitwise AND operator, when initializing
sdma virtual memory when using SDMA queues

firmwares are loaded by SMU on Tonga/Carrzio/Iceland
