MIPS: Refactor 'clear_page' and 'copy_page' functions.
Remove usage of the '__attribute__((alias("...")))' hack that aliased
to integer arrays containing micro-assembled instructions. This hack
breaks when building a microMIPS kernel. It also makes the code much
easier to understand.
[ralf@linux-mips.org: Added back export of the clear_page and copy_page
symbols so certain modules will work again. Also fixed build with
CONFIG_SIBYTE_DMA_PAGEOPS enabled.]
