drm/i915/guc: Change values for i915_guc_log_control 

Today we have format mismatch between read/write operations
of i915_guc_log_control entry. For read we return (0, 1..4)
that represents disable/verbosity levels, but for write we
force user to follow internal structure format (0,1,9,11,13).
Let's hide internals from the user and accept same values
as we support for read and related guc_log_level modparam.
