esp.c: only allow ESP commands permitted in the current asc_mode
If an ESP command is issued in an incorrect mode then an illegal command
interrupt should be generated. Add a new esp_cmd_is_valid() function to
indicate whether the ESP command is valid for the current mode, and if not
then raise the illegal command interrupt.

This fixes WinNT MIPS which issues ICCS after a Chip Reset which is not
permitted, but will fail with an INACCESSIBLE_BOOT_DEVICE error unless an
interrupt is generated.
