[PULL,35/44] hw/intc: openpic: Drop Raven related codes

Commit Message

From: Bin Meng <[e-mail]>

There is no machine that uses Motorola MCP750 (aka Raven) model.
Drop the related codes.

While we are here, drop the mentioning of Intel GW80314 I/O
companion chip in the comments as it has been obsolete for years,
and correct a typo too.
