MIPS: cavium-octeon: fix early boot hang on EBH5600 board
The boot hangs early on EBH5600 board when octeon_fdt_pip_iface() is
trying enumerate a non-existant interface. The actual hang happens in
cvmx_helper_interface_get_mode():
mode.u64 = cvmx_read_csr(CVMX_GMXX_INF_MODE(interface));
when interface == 4. We can avoid this situation by first checking that
the interface exists in the DTB.
