[POWERPC] spufs: Add runcntrl read accessors
This change adds a read accessor for the SPE problem-state run control
register.
This is required for for applying (userspace) changes made to the run
control register while the SPE is stopped - simply asserting the master
run control bit is not sufficient. My next patch for isolated-mode
setup requires this.
