m68k/atari: EtherNAT - platform device and IRQ support code
Add platform device and interrupt definitions necessary for the EtherNAT Ethernet/USB adapter for the Falcon extension port. EtherNAT interrupt numbers are 139/140 so the max. interrupt number for Atari has to be increased.

* different m68k hosts compiled into the kernel.
* Currently the Atari has 72 and the Amiga 24, but if both are
* supported in the kernel it is better to make room for 72.
+ * With EtherNAT add-on card on Atari, the highest interrupt
+ * number is 140 so NR_IRQS needs to be 141.
