Add "andestech,cpu-intc" compatible string to indicate that
Andes specific local interrupt is supported on the core,
e.g. AX45MP cores have 3 types of non-standard local interrupt
can be handled in supervisor mode:

- Slave port ECC error interrupt
- Bus write transaction error interrupt
- Performance monitor overflow interrupt

These interrupts are enabled/disabled via a custom register
SLIE instead of the standard interrupt enable register SIE.
