i915 expects GuC log level to be specified as:
0: disabled
1: enabled (verbosity level 0 = min)
2: enabled (verbosity level 1)
3: enabled (verbosity level 2)
4: enabled (verbosity level 3 = max)
Remove the earlier internal layout based logging control from
guc_log_control and send new expected values.
v2: log_level assert in guc_log_control, cleaner level setup (Michal)
added missing copyright header. (Sagar)
