MIPS: MIPS16e2: Report ASE presence in /proc/cpuinfo

Only now that both feature determination and unaligned emulation is in
place add reporting to /proc/cpuinfo, so that the presence of "mips16e2"
there not only indicates our recognition of the hardware feature, but
correct unaligned emulation as well.
