media: atomisp: Replace V4L2_PIX_FMT_RGB32 with V4L2_PIX_FMT_RGBX32

V4L2_PIX_FMT_RGB32 is deprecated because its definition never made
clear if the 4th byte was alpha data or unused. Instead either
V4L2_PIX_FMT_ARGB32 or V4L2_PIX_FMT_RGBX32 should be used.

V4L2_PIX_FMT_RGB32 internally is mapped to IA_CSS_FRAME_FORMAT_RGBA888
and ia_css_frame_format.h says that the alpha bits there are unused,
so replace V4L2_PIX_FMT_RGB32 with V4L2_PIX_FMT_RGBX32.
