MIPS: IP27: Fix build error with CONFIG_MAPPED_KERNEL
Some of the TLB bit definitions in <asm/pgtable-bits.h> have become rather
complex and are no longer usable from assembler resulting in an
explosion like this:

make[2]: *** [arch/mips/kernel/head.o] Error 1
Since now MAPPED_KERNEL_SETUP_TLB is in platform-specific code it's safe
to hardcode the TLB bits there.
