Subject: [PATCH v3 0/2] media: Add colors' order and other info over test image

This patchset aims to add a method to display the correct order of
colors for a test image generated. It does so by adding a function
which returns a string of correct order of the colors for a test
pattern. It then adds a control in vimc which displays the string 
over test image. It also displays some other information like saturation,
hue, contrast and brightness over test image generated by vimc.

Changes since v3:
	In 1st patch:
	-Improved formatting of returned string.

	In 2nd patch:
	 - Add CID prefix in control name and change it to a more
	   generic name.
	 - Rename bool variable to a generic name.
	 - Disable text rendering instead of stopping stream if no
	   font found.
	 - Display more info like VIVID in VIMC.

Changes since v2:
	In 1st patch:
	- Create a 'define' to prevent repetition of the common color
          sequence string.
        - Use 'fallthrough' on case statement to prevent repetition of
          code.

Changes since v1:
        - Divided the patch into two patches.
        - Returned NULL for patterns whose color order cannot be
          defined. (Reported-by: kernel test robot <lkp@...el.com>)
        - Made separate switch cases for separate test patterns
         (Reported-by: kernel test robot <lkp@...el.com>)
        - Renamed variables from camelcase to use '_'
        - prefixed 'media' to the patches.
