MLK-19510: ISI: fix isi cann't restore to original size after resize

1. add CHNL_SCL_IMG_CFG register that is new added in QXP/QM B0
2. according to isi owner's comments, CHNL_SCL_IMG_CFG need to
equal to CHNL_IMG_CFG when scaling disabled and equal to scaled
image size when scaling enabled, so add configuration for this
register.
3. Becuse isi software reset can't reset isi register to default
, so it need to manual clear if there is no scaling.
