media: rockchip: rga: Introduce color fmt macros and refactor CSC mode logic 

This introduces two macros: RGA_COLOR_FMT_IS_YUV and RGA_COLOR_FMT_IS_RGB
which allow quick checking of the colorspace familily of a RGA color format.

These macros are then used to refactor the logic for CSC mode selection.
The two nested tests for input colorspace are simplified into a single one,
with a logical and, making the whole more readable.
