target/xtensa: implement NMI support
When NMI is configured it is taken regardless of INTENABLE SR contents, PS.INTLEVEL or PS.EXCM. It is cleared automatically once it's taken. Add nmi_level to XtensaConfig, puth there NMI level from the overlay or XCHAL_NUM_INTLEVELS + 1 when NMI is not configured. Add NMI mask to INTENABLE SR and limit CINTLEVEL to nmi_level - 1 when determining pending IRQ level in check_interrupt(). Always take and clear pending interrupt at nmi_level in the handle_interrupt(). Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
