Update bcm config file system_ref_core_clock_khz param for j2cplus linecards

[skbarista]

Update the bcm config file system_ref_core_clock_khz param to handlesystems with J2cplus linecards.

We need system_ref_core_clock_khz to be set to 1600000 for supporting j2 and j2cplus linecards on the same chassis.
