This is a 10/100 ethernet device that has several features.
Only the ones needed by the Linux driver have been implemented.
See npcm7xx_emc.c for a list of unimplemented features.

Differences from v2:

1/3 hw/net: Add npcm7xx emc model

- move call to qemu_set_irq
- remove use of C99 mixed decls/statements
- add use of g_autofree

2/3 hw/arm: Add npcm7xx emc model

- none, patch ok as is

3/3 tests/qtests: Add npcm7xx emc model test

- remove use of C99 mixed decls/statements

Dropped again; the new tests fail on big-endian hosts (s390x, ppc64):
