[V1,0/2] Fix WLED FSC Sync and brightness Sync settings

Message

The FSC (Full scale current) setting is not updated properly due to the
wrong register toggling for WLED5. Also the ILED_SYNC toggle and MOD_SYNC
toggle sequence is updated as per the hardware team recommendation to fix
the FSC update and brightness update issue.
