Changes in v7:
- s/strlcpy/strscpy
- s/strcpy/strscpy
- fix config lsc error
LSC data table size is 17x17, but when configuring data to ISP,
should be aligned to 18x17. That means every last data of last
line should be filled with 0, and not filled with the data of
next line.
- Update new ISP parameters immediately
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.
- fix some ISP parameters config error
Some ISP parameter config functions may override the old enable
bit value, because the enable bits of these modules are in the
same registers with parameters. So we should save the old enable
bits firstly.
- code styling and checkpatch fixes
