ENGR00215884-1 MX6 SabreSD:Refine OV mipi camera reset sequence
This patch refines OV mipi camera reset sequence according to
OV's recommendation:
reset --------------------|_____|----------------
->| 1ms |<-
pwdn ----------|_________________________|------
->| 5ms |<- ->| 5ms |<-
->| 5ms |<-
This change makes the OV mipi camera be at a correct status
after reset, otherwise, the wrong status of OV mipi camera
will reduce the ~2.78V analog camera power to ~2.3V, which
causes random thin colorful lines on OV5642 CSI camera image
as OV5642 CSI camera uses the same analog power.
