* introduce RGB and packed YUV formats since the Hantro encoder
supports those
* remove hardware specific public headers since they only added
tiled pixel formats; instead, migrate these tiled formats into
ImxVpuApiColorFormat
* imx8 hantro decoder: reorder list of supported decoder color
formats to favor 10 bit output
* imx8 hantro decoder: clear new framebuffer fields to zero
* imx8 hantro encoder: fix segfault caused by trying to unmap
non existing staged raw frame
