Peter Maydell 293c76cb48 target/xtensa: SR reorganization and options for modern cores
Reorganize special register handling to support configurations with
 conflicting SR definitions.
 
 Implement options used by the modern xtensa cores:
 - memory protection unit;
 - block prefetch;
 - exclusive access
 
 Add special register definitions and IRQ types for ECC/parity,
 gather/scatter and IDMA.
