[PATCH linux v4 2/4] Barreleye SCU88 Setup to do_barreleye_setup

[OpenBMC Patches]

From: Adi Gangidi <adi.gangidi at rackspace.com>

I moved the Barreleye SCU88 Setup to do_barreleye_setup.  This way the SCU88 value gets overwritten to 0x01C00000 only for Barreleye. For Palmetto it remains what it was previously.

SCU 90 Setup though is common for chip sets we have, so it still remains in common setup.
