Dont worry about PSL_RI (restartable interrupt indicator) in

Browse Source 
common PowerPC code when all we want to achieve is to enable
external interrupts. We can set PSL_RI at any time before we
allow interrupts and/or exceptions, so move it to the AIM
specific initialization and do it when we also set PSL_ME
(machine check enable).
