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.
