The ordering of the params should be consistent with that of 
test_scaler_with_pixel_format_pipe and check_scaling_pipe_plane_rot.

Should move this inside of the for each loop since the compatible 
outputs are populated within for_each_pipe_with_single_output. Getting 
the mode before then will return incorrect values and cause an invalid 
argument error for create_fb.

This could hit an edge case where the resolution being passed in isn't 
32-bit aligned. Should add a check for this (maybe within 
check_scaling_pipe_plane_rot) and possibly correct to an appropriate fb 
size.
