util/hda-decoder: Add feature to print configuration defaults as verbs

Browse source 
This feature simply goes through pin configurations stored in a file and
converts them into their corresponding verbs. This can be useful when
trying to find verb data stored inside a binary (e.g. when reverse
engineering).

Input:
	0x16 0x04211040
	0x17 0x91170110
	0x18 0x40f001f0

Output:
	address: 0, node ID: 0x16, configuration default: 0x04211040
	  0x01671c40
	  0x01671d10
	  0x01671e21
	  0x01671f04
	address: 0, node ID: 0x17, configuration default: 0x91170110
	  0x01771c10
	  0x01771d01
	  0x01771e17
	  0x01771f91
	address: 0, node ID: 0x18, configuration default: 0x40f001f0
	  0x01871cf0
	  0x01871d01
	  0x01871ef0
	  0x01871f40
