James Hogan 8af0e3c2e8 KVM: MIPS/Emulate: Fix CACHE emulation for EVA hosts ...

Use protected_writeback_dcache_line() instead of flush_dcache_line(),
and protected_flush_icache_line() instead of flush_icache_line(), so
that CACHEE (the EVA variant) is used on EVA host kernels.

Without this, guest floating point branch delay slot emulation via a
trampoline on the user stack fails on EVA host kernels due to failure of
the icache sync, resulting in the break instruction getting skipped and
execution from the stack.
