Now that relay_open() accepts const callbacks, make relay callbacks const.

Start using device specific parameters instead of module parameters for
most things. The module parameters become the immutable initial values
for i915 parameters. The device specific parameters in i915->params
start life as a copy of i915_modparams. Any later changes are only
reflected in the debugfs.
The stragglers are:
* i915.force_probe and i915.modeset. Needed before dev_priv is
available. This is fine because the parameters are read-only and never
modified.
* i915.verbose_state_checks. Passing dev_priv to I915_STATE_WARN and
I915_STATE_WARN_ON would result in massive and ugly churn. This is
handled by not exposing the parameter via debugfs, and leaving the
parameter writable in sysfs. This may be fixed up in follow-up work.
* i915.inject_probe_failure. Only makes sense in terms of the module,
not the device. This is handled by not exposing the parameter via
debugfs.

uC is a component of the GT, so it makes sense for the uC debugfs files
to be in the GT folder. A subfolder has been used to keep the same
structure we have for the code.
v2: use intel_* prefix (Jani), rebase on new gt_debugfs_register_files,
fix permissions for writable debugfs files.
v3: Rename files (Michal), remove blank line (Jani), fix sparse warns.

Move the printers to the respective files for clarity. The
guc_load_status debugfs has been squashed in the guc_info one, has
having separate ones wasn't very useful. The HuC debugfs has been
renamed huc_info to match.

Creating and opening the GuC log relay file enables and starts
the relay potentially before the caller is ready to consume logs.
Change the behavior so that relay starts only on an explicit call
to the write function (with a value of '1'). Other values flush
the log relay as before.
v2: Style changes and fix typos. Add guc_log_relay_stop()
function. (Daniele)

Avoid going to the base i915 device when we already have a path from gt
to the runtime powermanagement interface. The benefit is that it looks a
bit more self-consistent to always be acquiring the gt->uncore->rpm for
use with the gt->uncore.

As we plan to continue driver load after GuC initialization
failure, we can't assume that GuC log data will be available
just because GuC was initially enabled. We must check that
GuC is still running instead.

It used to be handy that we only had a couple of headers, but over time
i915_drv.h has become unwieldy. Extract declarations to a separate
header file corresponding to the implementation module, clarifying the
modularity of the driver.
Ensure the new header is self-contained, and do so with minimal further
includes, using forward declarations as needed. Include the new header
only where needed, and sort the modified include directives while at it
and as needed.
No functional changes.
