Patch file for the photography extenstion

Current gstreamer photography interface supports a limited image effects
setting. Some features such as noise reduction, some colur effects are
available in some digital camera device and will be supported by the ISP on
Intel Atom platforms. These featue doesn't support by photography interface. 
The patch in the attachment will extend following two features.

1. extend the “GstColourToneMode “ structure to support sky blue, grass green,
skin whiten, emboss image effect and sketch image effect in the photography
interface when do the image capture through gstreamer.
The color effects are listed as in below, we are proposing to extend
“GstColourToneMode” to support them.
GST_PHOTOGRAPHY_COLOUR_TONE_MODE_SKY_BLUE: make sky looks more blue
GST_PHOTOGRAPHY_COLOUR_TONE_MODE_GRASS_GREEN : make grass looks more green
GST_PHOTOGRAPHY_COLOUR_TONE_MODE_SKIN_ WHITEN: make skin looks more whiten.
GST_PHOTOGRAPHY_COLOUR_TONE_MODE_ EMBOSS: emboss image effect
GST_PHOTOGRAPHY_COLOUR_TONE_MODE_ SKETECH: sketch image effect

2. support the noise reduction setting in the photography interface. 
We are proposing to add an entry “nr_mode” to GstPhotoSettings to support the
following noise reduction setting.
#define GST_PHOTOGRAPHY_BAYER_NR_MODE    1<< 0
#define GST_PHOTOGRAPHY_YCC_NR_MODE    1<< 1
#define GST_PHOTOGRAPHY_TEMPORAL_NR_MODE    1<< 2
#define GST_PHOTOGRAPHY_FPN_NR_MODE    1<< 3
#define GST_PHOTOGRAPHY_EXTRA_NR_MODE    1<< 4
