[PATCH 5/7] hw/mips/malta: Introduce the 'malta-phys' machine

["Philippe Mathieu-Daudé" <f4bug@amsat.org>]

Introduce the 'malta-phys' machine, aiming to have the same
limitations as real hardware. Start by restricting the RAM
to 1GB, which is the maximum amount of memory the GT-64120A
north bridge can address.
