Leonid Yegoshin 6575b1d417 MIPS: kernel: cpu-probe: Detect unique RI/XI exceptions 
Detect if the core supports unique exception codes for the
Read-Inhibit and Execute-Inhibit exceptions and set the
option accordingly. The RI/XI exception support is detected
by setting the 27th bit (IEC) of the PageGrain C0 register
and reading back the value of that register to verify the
bit is enabled.
