I can't find any description for unused McBSP in TI spec.

If i didn't use McBSP interface, what do i do for McBSP.

Pull high , pull low  or floating?

    The McBSP pins have internal pull down resistors as specified in Table 2-19 part 10 in the data manual (SPRS814A). If you are not using the interface it can be left unconnected.  The McBSP is a highly programmable serial interface that can support connections to many different devices.  The signals and programming of the interface are described in the Multichannel Buffered Serial Port (McBSP) User's Guide for KeyStone Devices which is available on the C6657 webpage.
