[Ricardo Ribalda Delgado <ricardo.ribalda@xxxxxxxxx>]

Add HSV encoding names to v4l2-ctl. I.e.

Format Video Capture:
	Width/Height      : 640/360
	Pixel Format      : 'HSV3'
	Field             : None
	Bytes per Line    : 1920
	Size Image        : 691200
	Colorspace        : sRGB
	Transfer Function : Default
	YCbCr/HSV Encoding: Hue 0 - 179
	Quantization      : Default
	Flags             :
