[MIPS] Sibyte: resurrect old cache hack.
The recent switch of the Sibyte SOCs from the processor specific cache
managment code in c-sb1.c to c-r4k.c lost this old hack
[MIPS] Hack for SB1 cache issues
Removing flush_icache_page a while ago broke SB1 which was using an
empty
flush_data_cache_page function. This glues things well enough so a more
efficient but also more intrusive solution can be found later.

in the hope it was no longer needed. As it turns it still is so resurrect
it until there is a better solution.
