MIPS: MSPxxxx: define MIPS34K_MISSED_ITLB_WAR for other PMC-Sierra SoC

Trying to build a PMC-Sierra MSP4200 VoIP gateway defconfig will not work
since MIPS34K_MISSED_ITLB_WAR is not defined for all boards supported
within pmc-serria/msp71xx. This patch defines MIPS34K_MISSED_ITLB_WAR to
prevent such build failures:

CHK include/linux/version.h
CHK include/linux/utsrelease.h
SYMLINK include/asm -> include/asm-mips
CC arch/mips/kernel/asm-offsets.s
In file included fromlinux-msp71xx/linux-2.6.29/arch/mips/include/asm/bitops.h:24,

linux-msp71xx/linux-2.6.29/arch/mips/include/asm/war.h:241:2: error: #error Check setting of MIPS34K_MISSED_ITLB_WAR for your
platform

This fixes a compile error when building for the MSP4200 boards. Identical
