msm: camera: isp: Reorder the stream on sequence in LCR use case

Due to timing protocol constraints between LCR and PD resources and
sof retiminig disabled, PPP resource should be enabled after RDI0
whenever LCR is enabled.
This commit changes the order during the CSID start to enable PPP
after RDI0.
