When cpu read or write extioi COREISR reg, it should access
the reg belonged to itself, so the cpu index of 's->coreisr'
is current cpu number. Using MemTxAttrs' requester_id to get 
the cpu index.

Changes for v6:
Only using MemTxAttrs' requester_id to get the cpu index
in LoongArch extioi access function. we do not based on 
the 'MemTxAttrs requester_type patch' so far, and when that
patch merged we will apply it quickly.

Changes for v5: 
These changes are following Philippe Mathieu-Daude's advice.
1. Add trace_bad_read/write function when MemTxAttrs type is
   not MTRT_CPU in extioi_read/write().
2. Separate 'remove unused extioi system memory region' to a
   single patch.

Changes for v4: 
Add 'reviewed-by' tag in fixing ipi patch, and other changes
are the same as v3. 
1. Remove the memmap table patch in this series, it
   will apply until we have more than one machinestate.
2. Using MemTxAttrs' requester_type and requester_id
   to get current cpu index in loongarch extioi regs
   emulation.
   This patch based on: 
   20220927141504.3886314-1-alex.bennee@linaro.org
3. Rewrite the commit message of fixing ipi patch, and 
   add reviewed by tag in the patch.
