The ISP8000Nano, found in the i.MX8MP, has a different architecture to crop at the resizer input. Instead of the "dual crop" block between the ISP and the resizers found in the RK3399, cropping has been moved to the input of the resizer blocks. As a result, the resizer CFG_UPD and CFG_UPD_AUTO bits have been moved to make space for a new CROP_ENABLE bit. Fix the resizer shadow update accordingly, using the DUAL_CROP feature to infer whether or not the resizer implements cropping. Support for resizer cropping itself will be added in a subsequent commit.
