media: rockchip: isp1: Update new ISP parameters immediately

Browse Source 
For those sub modules that have shadow registers in core isp, the
new programing parameters would not be active if both
CIF_ISP_CTRL_ISP_CFG_UPD_PERMANENT and CFG_UPD are not set. Now
we configure CFG_UPD to force update the shadow registers when new
ISP parameters are configured.

BUG=b:36227021
TEST=scarlet can preview, LSC data table can be switched.
