Track every intel_gt_pm_get() until its corresponding release in
intel_gt_pm_put() by returning a cookie to the caller for acquire that
must be passed by on released. When there is an imbalance, we can see who
either tried to free a stale wakeref, or who forgot to free theirs.
v2: track recently added calls in gen8_ggtt_bind_get_ce and

Beside reusing existing code, the main advantage of ref_tracker is
tracking per instance of wakeref. It allows also to catch double
put.
On the other side we lose information about the first acquire and
the last release, but the advantages outweigh it.

The GSC CS is not exposed to the user, so we skipped assigning a uabi
class number for it. However, the trace logs use the uabi class and
instance to identify the engine, so leaving uabi class unset makes the
GSC CS show up as the RCS in those logs.
Given that the engine is not exposed to the user, we can't add a new
case in the uabi enum, so we insted internally define a kernel
internal class as -1.
At the same time remove special handling for the name and complete
the uabi_classes array so internal class is automatically correctly
assigned.
Engine will show as 65535:0 other0 in the logs/traces which should
be unique enough.
v2:
* Fix uabi class u8 vs u16 type confusion.

On MTL, the HuC is only supported on the media GT, so our validation
check on the module parameter detects an inconsistency on the root GT
(the modparams asks to enable HuC, but the support is not there) and
prints the following info message:
[drm] GT0: Incompatible option enable_guc=3 - HuC is not supported!
This can be confusing to the user and make them think that something is
wrong when it isn't, so we need to silence it.
Given that any platform that supports HuC also supports GuC, if a user
tries to enable HuC on a platform that really doesn't support it they'll
already see a message about GuC not being supported, so instead of just
silencing the HuC message on newer platforms we can just get rid of it
entirely.

At the moment memory region names are a bit too varied and too
inconsistent to be used for ABI purposes, like for upcoming fdinfo
memory stats.
System memory can be either system or system-ttm. Local memory has the
instance number appended, others do not. Not only incosistent but thi
kind of implementation detail is uninteresting for intended users of
fdinfo memory stats.
Add a stable name always formed as $type$instance. Could have chosen a
different stable scheme, but I think any consistent and stable scheme
should do just fine.

The steering control and semaphore registers are inside an "always on"
power domain with respect to RC6. However there are some issues if
higher-level platform sleep states are entering/exiting at the same time
these registers are accessed. Grabbing GT forcewake and holding it over
the entire lock/steer/unlock cycle ensures that those sleep states have
been fully exited before we access these registers.
This is expected to become a formally documented/numbered workaround
soon.
Note that this patch alone isn't expected to have an immediately
noticeable impact on MCR (mis)behavior; an upcoming pcode firmware
update will also be necessary to provide the other half of this
workaround.
v2:
- Move the forcewake inside the Xe_LPG-specific IP version check. This
should only be necessary on platforms that have a steering semaphore.
