[PATCH 3.16.y-ckt 076/104] MIPS: CPS: #ifdef on CONFIG_MIPS_MT_SMP rather than CONFIG_MIPS_MT

[Luis Henriques]

3.16.7-ckt19 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Paul Burton <paul.burton@xxxxxxxxxx>

commit 7a63076d9a31a6c2073da45021eeb4f89d2a8b56 upstream.

The CONFIG_MIPS_MT symbol can be selected by CONFIG_MIPS_VPE_LOADER in
addition to CONFIG_MIPS_MT_SMP. We only want MT code in the CPS SMP boot
vector if we're using MT for SMP. Thus switch the config symbol we ifdef
against to CONFIG_MIPS_MT_SMP.
