target/ppc: restore powerpc_excp_booke doorbell interrupts

Browse Source 
This partially reverts commit 9dc20cc37d ("target/ppc: Simplify
powerpc_excp_booke"), which removed DOORI and DOORCI interrupts.
Without this patch, a -cpu e5500 -smp 2 machine booting Linux
crashes with:

  qemu: fatal: Invalid PowerPC exception 36. Aborting
