[Xen-ia64-devel][PATCH] evtchn_callback fix and clean

["Xu, Anthony" <anthony.xu@xxxxxxxxx>]

Since we had changed to use event callback to deliver interrupt,
      
1.the pending_interruption is changed to pending_event,
    
2.get_ivr, set_tpr, get_tpr and set_eoi are not used or only used
in the initialization phase. There is no need to write this code
in assembly. this code is deleted.

3.hyper_ssm_i needs to be rewritten to jump to entchn_callback_handler
intead of iva+0x3000 interrupt handler. I just disabled hyper_ssm_i,
and do this later.
