[MIPS] cpu/mips/cache.S: Introduce NESTED/LEAF/END macros
This patch replaces the current function definitions with NESTED, LEAF
and END macro. They specify some more additional information about the
function; an alignment of symbol, type of symbol, stack frame usage, etc.
These information explicitly tells the assembler and the debugger about
the types of code we want to generate.
