[PATCH 1/7] target/mips: Fix emulation of nanoMips MTHLIP instruction

[Stefan Pejic]

The field ac in nanoMips instruction MTHLIP rs, ac is specified in
nanoMips documentation as opcode[15..14] (2 bits). However, in the
current QEMU code, the corresponding argument passed to the helper
gen_helper_mthlip() has the value of opcode[15..11] (5 bits). Right
shift the value of this argument by three bits to fix this.
