Jiaxun Yang a1cd62883f avutil/mips: Use $at as MMI macro temporary register 
Some function had exceed 30 inline assembly register oprands limiation
when using LOONGSON2 version of MMI macros. We can avoid that by take
$at, which is register reserved for assembler, as temporary register.

As none of instructions used in these macros is pseudo, it is safe to
utilize $at here.
