[PATCH i-g-t 1/1] tools/intel_guc_logger: Send GuC log level in new i915 expected format

[Sagar Arun Kamble <sagar.a.kamble@xxxxxxxxx>]

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.
