[Intel-gfx] [PATCH] drm/i915/guc: Remove log size module parameters

[Joonas Lahtinen]

Remove the module parameters for configuring GuC log size.

We should instead rely on tuning the defaults to be usable for
reporting bugs.

Fixes: 8ad0152afb1b ("drm/i915/guc: Make GuC log sizes runtime configurable")
