target-mips: use ULL for 64 bit constants
Fix build on a 32 bit host:
CC mips-softmmu/target-mips/dsp_helper.o
/src/qemu/target-mips/dsp_helper.c: In function 'helper_dextr_rs_w':
/src/qemu/target-mips/dsp_helper.c:3556: error: integer constant is too large for 'long' type
/src/qemu/target-mips/dsp_helper.c: In function 'helper_extr_s_h':
/src/qemu/target-mips/dsp_helper.c:3656: error: integer constant is too large for 'long' type
