[PATCH v2 4/6] hw/mips/malta: Introduce the 'malta-strict' machine

[Philippe Mathieu-Daudé]

Introduce the 'malta-strict' machine, aiming to have the same
limitations as real hardware.

Start with 32 MB which is the default on the CoreLV, and allow
up to 256 MB which is the maximum this card can accept.

See datasheet 'MIPS Document Number: MD00051 Revision 01.07'.
