libavcodec: MIPS: MMI: Move sp out of the clobber list
GCC complains: warning: listing the stack pointer register ‘$29’ in a clobber list is deprecated [-Wdeprecated] Actually stack pointer was restored at the end of the inline assembly so there is no reason to add it to the clobber list. Also use $sp insted of $29 to make our intention much more clear.
